This update for gdb fixes the following issues:

GDB was updated to the 8.2 release:

- 'symbol-file' and 'add-symbol-file' accept -o to add relative
offset to all sections
- pager accepts 'c' response to disable it for rest of command
- accept _Alignof and alignof in C resp. C++ expressions
- new target riscv*-*-elf
- python API extensions: gdb.Type.align, gdb.execute deals
with multi-line gdb commands, gdb.convenience_variable and
gdb.set_convenience_variable to access convenience variables,
- aarch64: properly support hardware watchpoints on unaligned
addresses (needs kernel >= 4.10)
- Support access to new POWER8 registers [fate#325178, fate#326120]
- Support ipv6 for gdbserver connections.
- Update to intel processor trace library 2.0 (from 1.6.1).

Changes in the 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 debugger
