Tareq A. Siraj d88b9832c8 Add non-blocking Wait() for launched processes 
- New ProcessInfo class to encapsulate information about child processes.
- Generalized the Wait() to support non-blocking wait on child processes.
- ExecuteNoWait() now returns a ProcessInfo object with information about
  the launched child. Users will be able to use this object to
  perform non-blocking wait.
- ExecuteNoWait() now accepts an ExecutionFailed param that tells if execution
  failed or not.

These changes will allow users to implement basic process parallel
tools.

Rafael Espindola e03dfd9b0a Port GetMainExecutable over to PathV2. 
I will remove the V1 version as soon as I change clang in the next commit.

Rafael Espindola cb2eca0f91 Remove the program class. 
It was only used to implement ExecuteAndWait and ExecuteNoWait. Expose just
those two functions and make Execute and Wait implementations details.

Reid Kleckner 95012aaa93 Try to fix ProgramTest on FreeBSD 
This seemed like the cleanest way to find the test executable.  Also fix
the file mode.

Reid Kleckner 206ddd0734 Don't forward declare environ on Windows 
That seems to interact poorly with the environ and _environ macros
defined in MSVC's <stdlib.h>.

Also remove the incorrect comment about _NSGetEnviron().

Reid Kleckner de0c26046d Un-revert the environ copy in ProgramTest after fixing it on OS X 
This was r180041 and r180046, which was reverted in r180066.
Re-committing this should fix the dragonegg bootstrap, which I presume
needs LD_LIBRARY_PATH to be propagated to the child.

Tested on Linux, Windows, and Mac OS 10.6.

Michael Gottesman 6718a3b67d Revert "Add a missing reference on a std::vector<> out param" 
Revert "[Support] Propagate the environment into the test child process"

This reverts commit r180046.
This reverts commit r180041.

These have broken buildbots for ~3 hours:

Reid Kleckner 7ff21d934e Add a missing reference on a std::vector<> out param 
Pointed out by Eli.  The test passes for me either way, so I missed
this.

Reid Kleckner 21a8c2f361 [Support] Propagate the environment into the test child process 
Should fix the dragonegg bootstrap builder, which reasonably needs
LD_LIBRARY_PATH to be set.

Reid Kleckner 74679a93b2 [Support] Fix argv string escape bug on Windows 
Summary:
This is http://llvm.org/PR15802.  Backslashes preceding double quotes in
arguments must be escaped.  The interesting bit is that all other
backslashes should *not* be escaped, because the un-escaping logic is
only triggered by the presence of a double quote character.
