Subject: [PATCH] Sort includes for files gdb/[a-f]*.[chyl].

This patch sorts the include files for the files [a-f]*.[chyl].
The patch was written by a script.

Tested by the buildbot.

I will follow up with patches to sort the remaining files, by sorting
a subset, testing them, and then checking them in.
