We were just emitting "invalid module" w/o saying which module. That's
not particularly helpful.

TestCommandScript.py fails on Arm/Windows due following issues:
https://llvm.org/pr56288https://llvm.org/pr56292
LLDB fails to skip prologue and also step over library function or
nodebug functions fails due to PDB/DWARF mismatch.
This patch replace function breakpoint with line breakpoint so that we
can expect LLDB to stop on desired line. Also replace dwarf with PDB
debug info for this test only.
Eliminate boilerplate of having each test manually assign to `mydir` by calling
`compute_mydir` in lldbtest.py.

Protecting against accidental overwriting of commands is good, but
having to pass a flag to overwrite the command when developing your
commands is pretty annoying. This adds a setting to defeat the protection
so you can do this once at the start of your session and not have to
worry about it again.

Allow users to create aliases for aliases to raw input commands. That probably
sounds convoluted, so here's an example:
```
command alias some-setup env SOMEVAR=SOMEVALUE
```
This an alias based on `env`, which itself is an alias for `_regex-env`.
`_regex-env` is a `command regex` command, which takes raw input.
The above `some-setup` alias fails with:
```
error: Unable to create requested alias.
```
This change allows such aliases to be created. lldb already supports aliases to
aliases for parsed commands.

Fixes incomplete command names in `apropos` results.
The full command names given by `apropos` have come from command name string
literals given to `CommandObject` constructors. For most commands, this has
been accurate, but some commands have incorrect strings. This results in
`apropos` output that doesn't tell the user the full command name they might
want learn more about. These strings can be fixed.
There's a seperate issue that can't be fixed as easily: plugin commands. With
the way they're implemented, plugin commands have to exclude the root command
from their command name string. To illustrate, the `language objc` subcommand
has to set its command name string to "objc", which results in apropos printing
results as `objc ...` instead of `language objc ...`.
To fix both of these issues, this commit changes `FindCommandsForApropos` to
derive the fully qualified command name using the keys of subcommand maps.

(cherry picked from commit b3bfd595a548cd85b12e4e83729436cb73b26f29)
Unlike the rest of our SB objects, SBEvent and SBCommandReturnObject
have the ability to hold non-owning pointers to their non-SB
counterparts. This makes it hard to ensure the SB objects do not become
dangling once their backing object goes away.
While we could make these two objects behave like others, that would
require plubming even more shared pointers through our internal code
(Event objects are mostly prepared for it, CommandReturnObject are not).
Doing so seems unnecessarily disruptive, given that (unlike for some of
the other objects) I don't see any good reason why would someone want to
hold onto these objects after the function terminates.
For that reason, this patch implements a different approach -- the SB
objects will still hold non-owning pointers, but they will be reset to
the empty/default state as soon as the function terminates. This python
code will not crash if the user decides to store these objects -- but
the objects themselves will be useless/empty.

This starts to fix the other half of the lifetime problems in this code
-- dangling references. SB objects created on the stack will go away
when the function returns, which is a problem if the python code they
were meant for stashes a reference to them somewhere. Most of the time
this goes by unnoticed, as the code rarely has a reason to store these,
but in case it does, we shouldn't respond by crashing.
This patch fixes the management for a couple of SB objects (Debugger,
Frame, Thread). The SB objects are now created on the heap, and
their ownership is immediately passed on to SWIG, which will ensure they
are destroyed when the last python reference goes away. I will handle
the other objects in separate patches.
I include one test which demonstrates the lifetime issue for SBDebugger.
Strictly speaking, one should create a test case for each of these
objects and each of the contexts they are being used. That would require
figuring out how to persist (and later access) each of these objects.
Some of those may involve a lot of hoop-jumping (we can run python code
from within a frame-format string). I don't think that is
necessary/worth it since the new wrapper functions make it very hard to
get this wrong.

The point is to allow users with a related set of script based commands
to organize their commands in a hierarchy in the command set, rather than
having to have only top-level commands.

The old code incorrectly calculated the start position for the search
for the third (and subsequent) instance of a particular substitution
pattern (e.g. %1).
I also added a few test cases for this parsing covering this failure.
Make category-specifying files visible. There is really no good reason
to keep them hidden, and having them visible increases the chances
that someone will actually spot them.

This patch moves the `history` subcommand from the `command` to `session`
command. I think it makes more sense to have it there because as the `command`
usage suggests, it should be used to manage custom LLDB commands.
However, `history` is essentially tied to a debugging session and holds
all the commands (not specifically custom ones).
This also makes it more discoverable by adding an alias for it (mimicking
the shell builtin).

Add the skipIfReproducer decorator to the remaining tests that fail to
replay because the GDB remote packets diverge during replay. This is
*not* expected and should be fixed, but figuring out exactly what caused
the divergence has proven pretty difficult to track down.
I've marked these tests as skipped for now so we can get clean results
and detect new regressions. I have no evidence to believe that these
failures have the same root cause, so I've not assigned them a PR.
Summary:
Around a third of our test sources have LLVM license headers. This patch removes those headers from all test
sources and also fixes any tests that depended on the length of the license header.
The reasons for this are:
* A few tests verify line numbers and will start failing if the number of lines in the LLVM license header changes. Once I landed my patch for valid SourceLocations in debug info we will probably have even more tests that verify line numbers.
* No other LLVM project is putting license headers in its test files to my knowledge.
* They make the test sources much more verbose than they have to be. Several tests have longer license headers than the actual test source.
For the record, the following tests had their line numbers changed to pass with the removal of the license header:

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.
