[PATCH 0/7] Import needed gnulib modules explicitly

[Yao Qi <yao@codesourcery.com>]

Nowadays, when we import a certain gnulib module, some other dependent
modules are imported as well.  Some of them are used by gdb, while some
are not.  However, we may not be aware of this fact.

In GDB, we should have a list of imported gnulib modules which are used
by GDB, so that it is clear to know what headers and api functions are
used from gnulib.

I go through all imported gnulib modules, and update update-gnulib.sh to
import modules used by GDB explicitly.  This is what this patch series
is doing.  Beside this, this patch series (patch 3 and patch 6) adjusts
code to not check header and api and use them directly.
