Summary: Adding this in line with "stopCommands" and "exitCommands" so that we can run commands at the end of the debugging session.

Summary:
Currently loading core files on lldb-vscode is broken because there's a check in the attach workflow that asserts that the PID is valid, which of course fails for this case.
Hence, I'm adding a "coreFile" argument for the attach request, which does the work correctly.
I don't know how to test it effectively so that it runs on the buildbots and the debugger can in fact makes sense of it. Anyway, the change has been relatively simple.

Summary:
When using source maps for a breakpoint, in order to find the actual source that breakpoint has resolved, we
need to use a query similar to what CommandObjectSource::DumpLinesInSymbolContexts does, which is the logic
used by the CLI to display the source line at a given breakpoint. That's necessary because from a breakpoint
location you only have an address, which points to the original source location, not the source mapped one.
in the setBreakpoints request handler, we haven't been doing such query and we were returning the original
source location, which was breaking the UX of VSCode, as many breakpoints were being set but not displayed
in the source file next to each line. Besides, clicking the source path of a breakpoint in the breakpoints
view in the debug tab was not working for this case, as VSCode was trying to open a non-existent file, thus
showing an error to the user.
Ideally, we should do the query mentioned above to find the actual source location to respond to the IDE,
however, that query is expensive and users can have an arbitrary number of breakpoints set. As a simpler fix,
the request sent by VSCode already contains the full source path, which exists because the user set it from
the IDE itself, so we can simply reuse it instead of querying from the SB API.
I wrote a test for this, and found out that I had to move SetSourceMapFromArguments after RunInitCommands in
lldb-vscode.cpp, because an init command used in all tests is `settings clear -all`, which would clear the
source map unless specified after initCommands. And in any case, I think it makes sense to have initCommands
run before anything the debugger would do.

Summary:
If no custom launching is used, lldb-vscode launches a program with an empty environment by default. In some scenarios, the user might want to simply use the same environment as the IDE to have a set of working environment variables (e.g. PATH wouldn't be empty). In fact, most DAPs in VSCode have this behavior by default. In other cases the user definitely needs to set their custom environment, which is already supported. To make the first case easier for the user (e.g. not having to copy the PATH to the launch.json every time they want to debug simple programs that rely on PATH), a new option is now offered. inheritEnvironment will launch the program copying its own environment, and it's just a boolean flag.

Summary:
This patch fixes logging to log incoming packets which was removed during a refactor.
We also enable logging to a "vscode.txt" file for each lldb-vscode test by creating the log file in the build artifacts directory for each test. This allows users to see the packets for their tests if needed and the log file is in a directory that will be removed after tests have been run.

Summary: The VS Code DAP expects on response for each breakpoint that was requested. If we responsd with multiple entries for one breakpoint the VS Code UI gets out of date. Currently the VS code DAP doesn't handle one breakpoint with multiple locations. If this ever gets fixed we can modify our code.

Summary:
The DAP has a completion request that has been unimplemented. It allows showing autocompletion tokens inside the Debug Console.
I implemented it in a very simple fashion mimicking what the user would see when autocompleting an expression inside the CLI.
There are two cases: normal variables and commands. The latter occurs when a text is prepepended with ` in the Debug Console.
These two cases work well and have tests.

attach request have field `attachCommands` to handle attach specific commands
add a corresponding one for launch request
if no launch command is provided, create a new target and launch; otherwise, execute the launch command

Patch by Wanyi Ye <kusmour@gmail.com>

rL357954 did increase `packet-timeout` 1sec -> 5secs. Which is IMO about the
maximum timeout reasonable for regular use. But for testsuite I think the
timeout should be higher as the testsuite runs in parallel and it can be run
even on slow hosts and with other load (moreover if it runs on some slow arch).
I have chosen 60 secs, that should be enough hopefully. Larger value could
make debugging with hanging `lldb-server` annoying.
This patch was based on this testsuite timeout:

A reproducer of the racy bug for send_recv():
# self.send_packet(command)

I guess `request_continue` was probably originally intended to be synchronous
but then it isn't and this code has been leftover there.

D55859 <https://reviews.llvm.org/D55859> has no effect for some of the
testcases so this patch extends it even for (all?) other testcases known to me.
LLDB was failing when LLDB prints errors reading system debug infos
(`*-debuginfo.rpm`, DWZ-optimized) which should never happen as LLDB testcases
should not be affected by system debug infos.
`lldb/packages/Python/lldbsuite/test/api/multithreaded/driver.cpp.template` is
using only SB API which does not expose `ModuleList` so I had to call
`HandleCommand()` there.
`lldb-test.cpp` could also use `HandleCommand` and then there would be no need
for `ModuleListProperties::SetEnableExternalLookup()` but I think it is cleaner
with API and not on based on text commands.

Summary:
This change prevents the lldb-vscode test harness from hanging up waiting for
new messages when the lldb-vscode subprocess crashes.
Now, when an EOF from the subprocess pipe is detected we enqueue a `None` packet
in the received packets list. Then, during the message processing loop, we can
use this `None` packet to tell apart the case where lldb-vscode has terminated
unexpectedly from the normal situation where no pending messages means blocking
and waiting for more data.
I believe this should be enough to fix the issues with these tests hanging on
multiple platforms. Once this lands, I'll prepare and test a separate change
removing the @skipIfLinux annotations.

This tool can be easily packaged up into a native extension and used with Visual Studio Code, and it can also be used by Nuclide
