* 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
