Summary:
This patch adds SWIG typemaps that can convert arbitrary python
file objects into lldb_private::File.
A SBFile may be initialized from a python file using the
constructor. There are also alternate, tagged constructors
that allow python files to be borrowed, and for the caller
to control whether or not the python I/O methods will be
called even when a file descriptor is available.I

Summary:
Python APIs nearly all can return an exception. They do this
by returning NULL, or -1, or some such value and setting
the exception state with PyErr_Set*(). Exceptions must be
handled before further python API functions are called. Failure
to do so will result in asserts on debug builds of python.
It will also sometimes, but not usually result in crashes of
release builds.
Nearly everything in PythonDataObjects.h needs to be updated
to account for this. This patch doesn't fix everything,
but it does introduce some new methods using Expected<>
return types that are safe to use.

Seems I wrongly merged an old patch.
Reverts the change related to python dir for windows.
FileSpec should always contain normalized path. I.e. using '/' even in
windows.

Based on mgorny@'s D67890
There are 3 places where python site-package path is calculated
independently:
1. finishSwigPythonLLDB.py where files are written to site-packages.
2. lldb/scripts/CMakeLists.txt where site-packages are installed.
3. ScriptInterpreterPython.cpp where site-packages are added to
PYTHONPATH.
This change creates the path once and use it everywhere. So that they
will not go out of sync.
Also it provides a chance for cross compiling users to specify the right
path for site-packages.

Summary:
This patch factors out File as an abstract base
class and moves most of its actual functionality into
a subclass called NativeFile. In the next patch,
I'm going to be adding subclasses of File that
don't necessarily have any connection to actual OS files,
so they will not inherit from NativeFile.

Summary:
SBFile is a scripting API wrapper for lldb_private::File
This is the first step in a project to enable arbitrary python
io.IOBase file objects -- including those that override the read()
and write() methods -- to be used as the main debugger IOStreams.
Currently this is impossible because python file objects must first
be converted into FILE* streams by SWIG in order to be passed into
the debugger.

Summary:
This patch removes File::SetStream() and File::SetDescriptor(),
and replaces most direct uses of File with pointers to File.
Instead of calling SetStream() on a file, we make a new file and
replace it.
My ultimate goal here is to introduce a new API class SBFile, which
has full support for python io.IOStream file objects. These can
redirect read() and write() to python code, so lldb::Files will
need a way to dispatch those methods. Additionally it will need some
form of sharing and assigning files, as a SBFile will be passed in and
assigned to the main IO streams of the debugger.
In my prototype patch queue, I make File itself copyable and add a
secondary class FileOps to manage the sharing and dispatch. In that
case SBFile was a unique_ptr<File>.
(here: https://github.com/smoofra/llvm-project/tree/files)
However in review, Pavel Labath suggested that it be shared_ptr instead.
(here: https://reviews.llvm.org/D67793)
In order for SBFile to use shared_ptr<File>, everything else should
as well.
If this patch is accepted, I will make SBFile use a shared_ptr
I will remove FileOps from future patches and use subclasses of File
instead.

Summary:
This patch converts FileSystem::Open from this prototype:
Status
Open(File &File, const FileSpec &file_spec, ...);
to this one:
llvm::Expected<std::unique_ptr<File>>
Open(const FileSpec &file_spec, ...);
This is beneficial on its own, as llvm::Expected is a more modern
and recommended error type than Status. It is also a necessary step
towards https://reviews.llvm.org/D67891, and further developments
for lldb_private::File.

lvm_private::File::GetStream() can fail if m_options == 0
It's not clear from the header a File created with a descriptor will be
not be usable by many parts of LLDB unless SetOptions is also called,
but it is.
This is because those parts of LLDB rely on GetStream() to use the
file, and that in turn relies on calling fdopen on the descriptor. When
calling fdopen, GetStream relies on m_options to determine the access
mode. If m_options has never been set, GetStream() will fail.
This patch adds options as a required argument to File::SetDescriptor
and the corresponding constructor.

Jim pointed out that the LLDB global variables should only be available
in interactive mode. When used from a command for example, their values
might be stale or not at all what the user expects. Therefore we want to
explicitly make these variables unavailable.

The LoadScriptingModule used by command script import wasn't
initializing the LLDB global variables (things like `lldb.frame` and
`lldb.debugger`). They would get initialized however when running the
interactive script interpreter or running a single script line (e.g.
`script print(lldb.frame)`). This patch fixes that by properly
initializing the globals when loading a Python module.

This patch replaces explicit calls to log::Printf with the new LLDB_LOGF
macro. The macro is similar to LLDB_LOG but supports printf-style format
strings, instead of formatv-style format strings.
So instead of writing:
if (log)
log->Printf("%s\n", str);
You'd write:
LLDB_LOG(log, "%s\n", str);
This change was done mechanically with the command below. I replaced the
spurious if-checks with vim, since I know how to do multi-line
replacements with it.

Summary:
NFC = [[ https://llvm.org/docs/Lexicon.html#nfc | Non functional change ]]
This commit is the result of modernizing the LLDB codebase by using
`nullptr` instread of `0` or `NULL`. See
https://clang.llvm.org/extra/clang-tidy/checks/modernize-use-nullptr.html
for more information.
This is the command I ran and I to fix and format the code base:
```
run-clang-tidy.py \
-header-filter='.*' \
-checks='-*,modernize-use-nullptr' \
-fix ~/dev/llvm-project/lldb/.* \
-format \
-style LLVM \
-p ~/llvm-builds/debug-ninja-gcc
```
NOTE: There were also changes to `llvm/utils/unittest` but I did not
include them because I felt that maybe this library shall be updated in
isolation somehow.
NOTE: I know this is a rather large commit but it is a nobrainer in most
parts.

This is part two of the change started in r359330. This patch moves the
ownership of the script interpreter from the command interpreter into
the debugger. I would've preferred to remove the lazy initialization,
however the fact that the scripting language is set after the debugger
is created makes that tricky. So for now this does exactly the same
thing as when it was under the command interpreter. The result is that
this patch is fully NFC.

As discussed in D61090, there's no good reason for the script
interpreter to depend on the command interpreter. When looking at the
code, it becomes clear that we mostly use the command interpreter as a
way to access the debugger. Hence, it makes more sense to just pass that
to the script interpreter directly.
This is part 1 out of 2. I have another patch in the pipeline that
changes the ownership of the script interpreter to the debugger as well,
but I didn't get around to finish that today.

A lot of comments in LLDB are surrounded by an ASCII line to delimit the
begging and end of the comment.
Its use is not really consistent across the code base, sometimes the
lines are longer, sometimes they are shorter and sometimes they are
omitted. Furthermore, it looks kind of weird with the 80 column limit,
where the comment actually extends past the line, but not by much.
Furthermore, when /// is used for Doxygen comments, it looks
particularly odd. And when // is used, it incorrectly gives the
impression that it's actually a Doxygen comment.
I assume these lines were added to improve distinguishing between
comments and code. However, given that todays editors and IDEs do a
great job at highlighting comments, I think it's worth to drop this for
the sake of consistency. The alternative is fixing all the
inconsistencies, which would create a lot more churn.

Summary:
Within .lldbinit, regex commands can be structured as a list of substitutions over
multiple lines. It's possible that this is uninentional, but it works and has
benefits.
For example:
command regex <command-name>
s/pat1/repl1/
s/pat2/repl2/
...
I use this form of `command regex` in my `~/.lldbinit`, because it makes it
clearer to write and read compared to a single line definition, because
multiline substitutions don't need to be quoted, and are broken up one per line.
However, multiline definitions result in usage instructions being printed for
each use. The result is that every time I run `lldb`, I get a dozen or more
lines of noise. With this change, the instructions are only printed when
`command regex` is invoked interactively, or from a terminal, neither of which
are true when lldb is sourcing `~/.lldbinit`.
