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

a function call at the core of the loop inline and removing unused
stack variables from an often called function. This doesn't improve things
much, the real saving will be by reducing the number of calls to this
function (100K+ when linking kimwitu++).

Include local FDHandle.h file now that FDHandle is local to this library
and not in lib/System/FileUtilities.

llvm-svn: 19108

FDHandle class (non-portable) moved here from lib/Support/FileUtilities

Move non-portable FDHandle class to its only user: lib/Debugger

Remove unix specific code (use of errno and read) from the reader.
