Add MDB Debugger to linux v4.5 (2016-03-14 15:17:44 -0600)

----------------------------------------------------------------
Signed GPG Tag for mdb-v4.5

Hi Linus,

Please consider one in-kernel debugger for 4.6 with full disassembler
for x86/x86_64 architectures systems. This code is fully checkpatch.pl
compliant and is essentially a complete rewrite of the eariler
version of this debugger. The code conforms to Linux coding standards
and these commits have been digitally signed with my published
GPG key.

Checkpatch results:

./scripts/checkpatch.pl --file --strict arch/x86/kernel/debug/mdb/*.[ch]
