Zachary Turner 190fadcdb2 Unicode support on Win32.
Win32 API calls that are Unicode aware require wide character
strings, but LLDB uses UTF8 everywhere.  This patch does conversions
wherever necessary when passing strings into and out of Win32 API
calls.

Jim Ingham 583bbb1dd4 Change over the broadcaster/listener process to hold shared or weak pointers
to each other.  This should remove some infrequent teardown crashes when the
listener is not the debugger's listener.

Processes now need to take a ListenerSP, not a Listener&.

This required changing over the Process plugin class constructors to take a ListenerSP, instead
of a Listener&.   Other than that there should be no functional change.

Adrian McCarthy a7ad58b61c NFC: Refactor ProcessWinMiniDump to use a more traditional pimpl idiom.
This is a mechanical refactor.  There should be no functional changes in this commit.

Instead of encapsulating just the Windows-specific data, ProcessWinMiniDump now uses a private implementation class.  This reduces indirections (in the source).  It makes it easier to add private helper methods without touching the header and allows them to have platform-specific types as parameters.  The only trick was that the pimpl class needed a back pointer in order to call a couple methods.

Adrian McCarthy 0a750820a3 Get register context for the 32-bit process in a WoW64 process minidump
32-bit processes on 64-bit Windows run in a layer called WoW64 (Windows-on-Windows64). If you capture a mini dump of such a process from a 32-bit debugger, you end up with a register context for the 64-bit WoW64 process rather than the 32-bit one you probably care about.

This detects WoW64 by looking to see if there's a module named wow64.dll loaded. For such processes, it then looks in the 64-bit Thread Environment Block (TEB) to locate a copy of the 32-bit CONTEXT record that the plugin needs for the register context.

Added some rudimentary tests.  I'd like to improve these later once we figure out how to get the exception information from these mini dumps.

Adrian McCarthy 6fadea62b5 Improve ReadRegister for RegisterContextWindowsx86
In some circumstances (notably, certain minidumps), the thread CONTEXT does not have values for the
control registers (EIP, ESP, EBP, EFLAGS).  There are flags in the CONTEXT which indicate which
portions are valid, but those flags weren't checked.  The old code would not detect this and give a
garbage value for the register.  The new code will log the problem and return an error.

I consolidated the error checking and logging into a helper function, which makes the big switch
statement easier to read and verify.

Ran tests to ensure this doesn't break anything.  Manually verified that a minidump without info on
the control registers now indicates the problem instead of giving bad information.

Zachary Turner 8d8033c3b4 Fix a race condition when terminating inferiors on Windows.
If a breakpoint was hit in the inferior after shutdown had
started but before it was complete, it would cause an unclean
terminate of the inferior, leading to various problems the most
visible of which is that handles to the inferior executable would
remain locked, and the test suite would fail to run subsequent
tests because it could not recompile the inferior.

This fixes a major source of flakiness in the test suite.

Zachary Turner ddf0661b38 Fix log disable command in ProcessWindowsLog.
The implications of this bug where that "log disable windows" would
not actually disable the log, and worse it would lock the file handle
making it impossible to delete the file until lldb was shut down.

This was then causing the test suite to fail, because the test suite
tries to delete log files in certain situations.

Jason Molenda 63bd0db071 Clean up register naming conventions inside lldb.
"gcc" register numbers are now correctly referred to as "ehframe"
register numbers.  In almost all cases, ehframe and dwarf register
numbers are identical (the one exception is i386 darwin where ehframe
regnums were incorrect).

The old "gdb" register numbers, which I incorrectly thought were
stabs register numbers, are now referred to as "Process Plugin"
register numbers.  This is the register numbering scheme that the
remote process controller stub (lldb-server, gdbserver, core file
support, kdp server, remote jtag devices, etc) uses to refer to the
registers.  The process plugin register numbers may not be contiguous
- there are remote jtag devices that have gaps in their register
numbering schemes.

I removed all of the enums for "gdb" register numbers that we had
in lldb - these were meaningless - and I put LLDB_INVALID_REGNUM
in all of the register tables for the Process Plugin regnum slot.

This change is almost entirely mechnical; the one actual change in
here is to ProcessGDBRemote.cpp's ParseRegisters() which parses the
qXfer:features:read:target.xml response.  As it parses register
definitions from the xml, it will assign sequential numbers as the
eRegisterKindLLDB numbers (the lldb register numberings must be
sequential, without any gaps) and if the xml file specifies register
numbers, those will be used as the eRegisterKindProcessPlugin
register numbers (and those may have gaps).  A J-Link jtag device's
target.xml does contain a gap in register numbers, and it only 
specifies the register numbers for the registers after that gap.
The device supports many different ARM boards and probably selects
different part of its register file as appropriate.

Summary:
This commit moves the Windows DyanamicLoader to the common DynamicLoader
directory. This is required to remote debug Windows targets.

This commit also initializes the Windows DYLD plugin in
SystemInitializerCommon (similarly to both POSIX and MacOSX DYLD
plugins) so that we can automatically instantiate this class when
connected to a windows process.
