Introduce common/common-defs.h

This commit creates a new header, common/common-defs.h, to hold
definitions common to all code under gdb/.  Both gdb/defs.h and
gdb/gdbserver/server.h are modified to include common-defs.h as
their first non-comment line; all code under gdb/ includes either
defs.h or server.h as appropriate, so common-defs.h will be the
first actual code the compiler sees.

For this initial commit common-defs.h includes only the two
config.h files.  Future commits will move more code currently
duplicated across defs.h and server.h such that shared code in
gdb/{common,target,nat} can be modified to include common-defs.h
rather than defs.h or server.h.
