Move gnulib to top level
This patch moves the gdb/gnulib subdirectory to the top level.
It adjusts the top-level build system to build gnulib when necessary,
and changes gdb to use this. However, gdbserver still builds its own
copy of gnulib, just from the new source location.
A small hack was needed to ensure that gnulib is only built when gdb
is enabled. The Makefile only provides an ordering -- the directory
must be mentioned in configdirs to actually be compiled at all.
Most of the patch is just a "git mv" of gnulib, though a few minor
path adjustments were needed in some files there.
Tested by the buildbot.
