assertRegexpMatches is a deprecated alias for assertRegex and has been
removed in Python 3.12. This wasn't an issue previously because we used
a vendored version of the unittest module. Now that we use the built-in
version this gets updated together with the Python version used to run
the test suite.

This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

There are two conditions for the loop exit. Either we hit LLDB_INVALID_ADDRESS
or the ABI tells us we are beyond mappable memory.
I made a mistake in that second part that meant if you had no ABI plugin
--all would stop on the first loop and return nothing.
If there's no ABI plugin we should only check for LLDB_INVALID_ADDRESS.
Depends on D134029

When I wrote the initial version I forgot that a region being
unmapped is not an error. There are real errors that we don't
want to hide, such as the remote not supporting the
qMemoryRegionInfo packet (gdbserver does not).

These two tests were each of them too long when running under ASAN,
so we have to skip both to get a clean ASAN bot run.

bot. This happens because they are building a long result into
a Python string, and the asan checker is making that very slow.
The last two tests here are both slow, but the 'test_command' is the
really slow one. I'm going to start disabling just that one and see
if that gets the ASAN bots clean.

As suggested in post-commit review on https://reviews.llvm.org/D129272.
* Rename the test case.
* Simplify the overlap check.
* Correct assertion.

Previously we recorded AllocationBase as the base address of the region
we get from VirtualQueryEx. However, this is the base of the allocation,
which can later be split into more regions.
So you got stuff like:
[0x00007fff377c0000-0x00007fff377c1000) r-- PECOFF header
[0x00007fff377c0000-0x00007fff37840000) r-x .text
[0x00007fff377c0000-0x00007fff37870000) r-- .rdata
Where all the base addresses were the same.
Instead, use BaseAddress as the base of the region. So we get:
[0x00007fff377c0000-0x00007fff377c1000) r-- PECOFF header
[0x00007fff377c1000-0x00007fff37840000) r-x .text
[0x00007fff37840000-0x00007fff37870000) r-- .rdata
https://docs.microsoft.com/en-us/windows/win32/api/winnt/ns-winnt-memory_basic_information
The added test checks for any overlapping regions which means
if we get the base or size wrong it'll fail. This logic
applies to any OS so the test isn't restricted to Windows.

This reverts commit 3e928c4b9dfb01efd2cb968795e605760828e873.
This fixes an issue seen on Windows where we did not properly
get the section names of regions if they overlapped. Windows
has regions like:
[0x00007fff928db000-0x00007fff949a0000) ---
[0x00007fff949a0000-0x00007fff949a1000) r-- PECOFF header
[0x00007fff949a0000-0x00007fff94a3d000) r-x .hexpthk
[0x00007fff949a0000-0x00007fff94a85000) r-- .rdata
[0x00007fff949a0000-0x00007fff94a88000) rw- .data
[0x00007fff949a0000-0x00007fff94a94000) r-- .pdata
[0x00007fff94a94000-0x00007fff95250000) ---
I assumed that you could just resolve the address and get the section
name using the start of the region but here you'd always get
"PECOFF header" because they all have the same start point.
The usual command repeating loop used the end address of the previous
region when requesting the next, or getting the section name.
So I've matched this in the --all scenario.
In the example above, somehow asking for the region at
0x00007fff949a1000 would get you a region that starts at
0x00007fff949a0000 but has a different end point. Using the load
address you get (what I assume is) the correct section name.

This adds an option to the memory region command
to print all regions at once. Like you can do by
starting at address 0 and repeating the command
manually.
memory region [-a] [<address-expression>]
(lldb) memory region --all
[0x0000000000000000-0x0000000000400000) ---
[0x0000000000400000-0x0000000000401000) r-x <...>/a.out PT_LOAD[0]
<...>
[0x0000fffffffdf000-0x0001000000000000) rw- [stack]
[0x0001000000000000-0xffffffffffffffff) ---
The output matches exactly what you'd get from
repeating the command. Including that it shows
unmapped areas between the mapped regions.
(this is why Process GetMemoryRegions is not
used, that skips unmapped areas)
Help text has been updated to show that you can have
an address or --all but not both.

Explicitly consider the libraries reported on the initial rendezvous
breakpoint hit added. This is necessary on FreeBSD since the dynamic
loader issues only a single 'consistent' state rendezvous breakpoint hit
for all the libraries present in DT_NEEDED. It is also helpful on Linux
where it ensures that ld-linux is considered loaded as well
as the shared system libraries reported afterwards.
Reenable memory maps on FreeBSD since this fixed the issue triggered
by them.

This reverts commit 09b08833f301ea375137931d26b7193101f82ceb.
This code is wrong on Linux, and causes ld-linux and linux-vdso to be
reported twice. I need to work on it more.

This reverts commit c65627a1fe3be7521fc232d633bb6df577f55269.
The test immediately after the new invalid symbol test was
failing on Windows. This was because when we called
VirtualQueryEx to get the region info for 0x0,
even if it succeeded we would call GetLastError.
Which must have picked up the last error that was set while
trying to lookup "not_an_address". Which happened to be 2.
("The system cannot find the file specified.")
To fix this only call GetLastError when we know VirtualQueryEx
has failed. (when it returns 0, which we were also checking for anyway)
Also convert memory region to an early return style
to make the logic clearer.

Previously when <addr> in "memory region <addr>" didn't
parse correctly, we'd print an error then also ask lldb-server
for a region containing LLDB_INVALID_ADDRESS.
(lldb) memory region not_an_address
error: invalid address argument "not_an_address"...
error: Server returned invalid range
Only send the command to lldb-server if the address
parsed correctly.

Summary: Moves lldbsuite tests to lldb/test/API.
This is a largely mechanical change, moved with the following steps:
```
rm lldb/test/API/testcases
mkdir -p lldb/test/API/{test_runner/test,tools/lldb-{server,vscode}}
mv lldb/packages/Python/lldbsuite/test/test_runner/test lldb/test/API/test_runner
for d in $(find lldb/packages/Python/lldbsuite/test/* -maxdepth 0 -type d | egrep -v "make|plugins|test_runner|tools"); do mv $d lldb/test/API; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-vscode -maxdepth 1 -mindepth 1 | grep -v ".py"); do mv $d lldb/test/API/tools/lldb-vscode; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-server -maxdepth 1 -mindepth 1 | egrep -v "gdbremote_testcase.py|lldbgdbserverutils.py|socket_packet_pump.py"); do mv $d lldb/test/API/tools/lldb-server; done
```
lldb/packages/Python/lldbsuite/__init__.py and lldb/test/API/lit.cfg.py were also updated with the new directory structure.
