Zachary Turner de963e9a09 Adds the notion of an OptionValidator.
The purpose of the OptionValidator is to determine, based on some
arbitrary set of conditions, whether or not a command option is
valid for a given debugger state.  An example of this might be
to selectively disable or enable certain command options that
don't apply to a particular platform.

This patch contains no functional change, and does not actually
make use of an OptionValidator for any purpose yet.  A follow-up
patch will begin to add the logic and users of OptionValidator.

Greg Clayton 100eb93f89 Add host layer support for pipes.
Windows does support pipes, but they do so in a slightly different way. Added a Host layer which abstracts the use of pipes into a new Pipe class that everyone can use.

Windows benefits include:
- Being able to interrupt running processes when IO is directly hooked up 
- being able to interrupt long running python scripts
- being able to interrupt anything based on ConnectionFileDescriptor

Todd Fiala af245d115b Add lldb-gdbserver support for Linux x86_64.
This change brings in lldb-gdbserver (llgs) specifically for Linux x86_64.
(More architectures coming soon).

Not every debugserver option is covered yet.  Currently
the lldb-gdbserver command line can start unattached,
start attached to a pid (process-name attach not supported yet),
or accept lldb attaching and launching a process or connecting
by process id.

The history of this large change can be found here:
https://github.com/tfiala/lldb/tree/dev-tfiala-native-protocol-linux-x86_64

Until mid/late April, I was not sharing the work and continued
to rebase it off of head (developed via id tfiala@google.com).  I switched over to
user todd.fiala@gmail.com in the middle, and once I went to github, I did
merges rather than rebasing so I could share with others.

Todd Fiala 6d6b55d153 Pull ProcessInfo and ProcessLaunchInfo out of Target/Process.
Elevate ProcessInfo and ProcessLaunchInfo into their own headers.
llgs will be using ProcessLaunchInfo but doesn't need to pull in
the rest of Process.h.

This also moves a bunch of implementation details from the header
declarations into ProcessInfo.cpp and ProcessLaunchInfo.cpp.

Tested on Ubuntu 14.04 Cmake and MacOSX Xcode.

Related to https://github.com/tfiala/lldb/issues/26.

successful resume for that part.  This will make the timeouts more stable when lldb is running

Jim Ingham 35878c4752 Fix the behavior when hand-calling a function times out on one thread,
but by the time we go to halt, it has already stopped by hitting the 
function end breakpoint.  That wasn't being shown to the threads so the
Function call thread plan didn't know its job was done.

Greg Clayton 6fea17e874 "size_t" isn't always 64 bit, it is 32 bit on 32 bit systems. All printf style statements that were assuming size_t were 64 bit were changed, and they were also changed to display them as unsigned values as "size_t" isn't signed.
If you print anything with 'size_t', please cast it to "uint64_t" in the printf and use PRIu64 or PRIx64.

I carefully reviewed exactly how the IOHandlers interact and found places where we weren't properly controlling things. There should be no overlapping prompts and all output should now come out in a controlled fashion.
