- Rebase to 8.1 release:
* ptype/o prints offsets and sizes of members (like pahole)
* tab-completion improved: quoting function names is not generally
necessary anymore, completion offers for breakpoint don't include
data symbol
* enable/disable breakpoints now accept ranges: 'disable 1.3-5'
* new commands:
- set/show cwd: working directory of debuggee
- set/show compile-gcc: program to use for 'compile' command
- starti: start program and stop at first instruction
- TUI single-key commands: 'i' for stepi and 'o' for nexti
* --readnever option disables any reading of debug info (for dumping)
* s390: guarded storage register access for z14
* gcore option -a dumps all memory mapping
* C++ breakpoints: 'b foo' will now set a breakpoint on all functions
and methods named 'foo' no matter the scope. Use -qualified if you
don't want that
* python scripting: new events gdb.new_inferior, gdb.inferior_deleted
and gdb.new_thread; new command rbreak (breakpoint accepting regexps)
* gdbserver can be passed environment parameters to remote debuggee
- Added patches from Fedora:
gdb-ppc64-stwux-tautological-compare.patch
gdb-rhbz1540559-gdbaddindex-glibcdebug-regression.patch
gdb-vla-intel-fix-print-char-array.patch
- Removed unused gdb-libstdc++-v3-python-7.1.1-20170526.tar.bz2
- Removed obsolete upstream patches:
gdb-s390x-1b63490.patch
gdb-s390x-289e23a.patch
gdb-s390x-8fe09d7.patch
gdb-s390x-96235dc.patch

The patch makes sense only with the build-id patchset so this is not submit
