Add a Mutex class for thread synchronization in a platform-independent way.
The current implementation only supports pthreads. Win32 use of Critical
Sections will be added later. The design permits other threading models to
be used if (and only if) pthreads is not available.

This chagne just renames some sys::Path methods to ensure they are not
misused. The Path documentation now divides methods into two dimensions:
Path/Disk and accessor/mutator. Path accessors and mutators only operate
on the Path object itself without making any disk accesses. Disk accessors
and mutators will also access or modify the file system. Because of the
potentially destructive nature of disk mutators, it was decided that all
such methods should end in the work "Disk" to ensure the user recognizes
that the change will occur on the file system. This patch makes that
change. The method name changes are:
makeReadable -> makeReadableOnDisk
makeWriteable -> makeWriteableOnDisk
makeExecutable -> makeExecutableOnDisk
setStatusInfo -> setStatusInfoOnDisk
createDirectory -> createDirectoryOnDisk
createFile -> createFileOnDisk
createTemporaryFile -> createTemporaryFileOnDisk
destroy -> eraseFromDisk
rename -> renamePathOnDisk
These changes pass the Linux Deja Gnu tests.

Get rid of the difference between file paths and directory paths. The Path
class now simply stores a path that can refer to either a file or a
directory. This required various changes in the implementation and interface
of the class with the corresponding impact to its users. Doxygen comments were
also updated to reflect these changes. Interface changes are:
appendDirectory -> appendComponent
appendFile -> appendComponent
elideDirectory -> eraseComponent
elideFile -> eraseComponent
elideSuffix -> eraseSuffix
renameFile -> rename
setDirectory -> set
setFile -> set
Changes pass Dejagnu and llvm-test/SingleSource tests.

gdb debugger doesn't get confused on which file it is reading (the one in
lib/System or the one in lib/System/{Win32,Unix})

* Move implementation of sys::PreventCoreFiles function to this file from
the now defunct SysConfig abstraction.

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.

* Implement GetMallocUsage to get usage of malloc heap
* Implement GetMemoryUsage to get total memory usage of process
* Implement GetTimeUsage to get elapsed/user/system time
