[Crash-utility] [PATCH v3 0/2] Update gdb to 10.1

Thanks, Kazu, for review. Really good catches! I addressed all of them and one extra. Here is updated patchset v3 (intermediate). v3 Changes: - Merged patch #3 (copyright message) into patch #1, edited to align with others. - "'bt' command often emits reduced output" - fixed. The issue was in provided by new gdb "call" mnemonic instead of expected "callq". Unwinder just didn't find the caller because of it. - "lack of information about struct members" and "unionprint" - fixed. The issue was in changed user_print_options members datatypes. Previously 4-bytes bool types now are 1-byte. Changed type of gdb_prettyprint_* from (int *) to (unsigned char *). Now, write access to such members do not clobber following members. - Commented back WARNING_OPTIONS in Makefile - Found and fixed one more issue: not working "p schedule" or "p &schedule". It was printing wrong address of the symbols. The address was relocated twice by kaslr_offset. It was fixed by disabling gdb symbols patching. I commented its invocation by "#if 0" and believe entire patching code can be safely removed. Benefits: less code to maintain, less hooks (such as bait_and_switch), faster load time. Let me know if it is safe to remove it, and I can integrate it with patch #1, gdb-10.1.patch will be even smaller. v2 Changes: Patch #1: - added crash_target with memory accessors. - instead of adding relocation offset in x86_64 initialization code, added symbol file rebasing. So GDB will understand real load addresses. Patch #2: New patch. Support gdb backtrace with input and local variables, frames walking. Patch #3. New patch. Adds VMware credits to the version banner.
