SysConf abstraction was pointless because it had a single function in it that
pertained only to the current process. So merge it into the Process abstraction
and remove the files completely.

Old versions of the C runtime somehow get loaded into the process.  Make
sure they aren't searched for symbols.

ltdl's LGPL license would infect all of LLVM.

Merge implementations of isValid and GetTemporaryDirectory into this file. There
is not any point having the operating system specific files for such little
variation between the Unix family of systems.

llvm-svn: 19134

This implementation is no longer needed, its been merged to Unix/Path.cpp since
there is such little variation between the platforms.

llvm-svn: 19133

Use the LLVM_ON_UNIX and LLVM_ON_WIN32 #defines to include the implementation
instead of relying upon the "platform" link

createTemporaryFile semantics where it doesn't create a fully unique name
if the basename doesn't exist. This functionality is now optionally
provided by the boolean reuse_current parameter to createTemporaryFile and
makeUnique. The default values differ because of the way these functions
are used in LLVM.
