58722cac5a value_bits_valid: Fix latent bug.
Doing something else, I factored out the bits of the value_bits_valid
function that actually handle the check_validity hook, and
surprisingly found out that the result was misbehaving.  Turns out
value_bits_valid has a latent bug.  If the value is not lval_computed,
or doesn't have a check_validity hook, then we should assume the value
is entirely valid, not invalid.  This is currently masked by the
value->optimized_out check -- I ran the testsuite with a gdb_assert(0)
inserted in place of that return being touched by the patch, and it
never triggers.

Tested on x86_64 Fedora 17.

17ef446eed On mainline/development, also link GDBserver with -lmcheck.
This factors --enable-libmcheck related bits from GDB's configure.ac
and makes GDBserver use them too.  Specifically, the 'development'
global is moved to a separate script to it can be sourced by both GDB
and GDBserver, and the --enable-libmcheck/--disable-libmcheck bits
proper are moved to a new m4 file.

I started out by defining 'development' in the m4 file, but in the end
decided against it, as a separate script has the advantage that
changing it in release branches does not require regenerating
configure, unlike today.

I had also started out by making the new GDB_AC_LIBMCHECK itself
handle the yes/no default fallback depending on release/developement,
but since I had split out 'development' to a separate script, and, GDB
needs the python checks anyway (hence we'd need to do the python
checks in gdb's configure.ac, and pass in a 'default lmcheck yes/no'
parameter to GDB_AC_LIBMCHECK anyway), I ended up keeping
GDB_AC_LIBMCHECK isolated from the 'development' global.  IOW, it's
the caller's business to handle it.

Tested on x86_64 Fedora 17.  Built GDB and GDBserver with and without
--enable-libmcheck, and observed --enable-libmcheck overrides the
disablement of -lmcheck caused by python supporting threads, and that
GDBserver links with -lmcheck when expected.  Also observed that
changing the 'development' global, and issuing "make" triggers a
relink, and '-lmcheck' is included or not from the link accordingly.

4db1a1dc03 change gdb to use BFD's "dwz" functions
BFD recently got a few functions related to "dwz" files.  This patch
