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:

On slower machines the vscode testcases were sometimes hanging:

A reproducer of the racy bug for send_recv():
# self.send_packet(command)
#+ import time
#+ time.sleep(1)
# done = False
I guess `request_continue` was probably originally intended to be synchronous
but then it isn't and this code has been leftover there.

Summary: lldb-mi has been removed, but there are still a bunch of references in the code base. This patch removes all of them.

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.

encode/decode the data before sending it over the socket. Since (AFAICT)
the vscode protocol (unlike the gdb-remote one) is fully textual, using
the utf8 codec here is appropriate.

This patch adds a new lldb-vscode tool that speaks the Microsoft Visual Studio Code debug adaptor protocol. It has full unit tests that test all packets.
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
