[PATCH v2 0/8] Python bindings for btrace recordings

[Tim Wiederhake <tim.wiederhake@intel.com>]

This patch series adds Python bindings for btrace recordings.

V1 of this series can be found here:
https://sourceware.org/ml/gdb-patches/2016-10/msg00733.html

Thanks to Eli and Simon for reviewing.  Issues in V1 and changes in V2:
- Rebased on current master
- Patch 3:
  - struct btrace_thread_info is memset to zero in some places.  The VEC member
    therefore can't be replaced by a std::vector at the moment.
  - The linked list in struct btrace_function will go away in a follow up patch
    series mentioned in Patch 3 "btrace: Use binary search to find instruction".
- Patch 4:
  - New patch to remove logic from gdbpy_start_recording.
- Patch 5 (was 4):
  - Commit message is now in present tense.
  - Fixed typo: Function is gone.
  - Variable in gdbpy_start_recording is now const.
  - gdbpy_start_recording is now recording method agnostic.
  - Python in target.{c,h}: I see no way around that. Ideas welcome.
    See https://sourceware.org/ml/gdb-patches/2016-10/msg00803.html
- Patch 7 (was 6):
  - Un-duplicated test name
  - Renamed py-record.{c,exp} -> py-record-btrace.{c,exp}
- Patch 8 (was 7):
  - Added references to process recording chapter.
  - gdb.start_recording () now takes two arguments.
  - Set brackets in roman typeface in documentation.
  - Made it more clear that parameters to gdb.start_recording are strings.

Tim Wiederhake (8):
  btrace: Count gaps as one instruction explicitly.
  btrace: Export btrace_decode_error function.
  btrace: Use binary search to find instruction.
  Add record_start function.
  python: Create Python bindings for record history.
  python: Implement btrace Python bindings for record history.
  python: Add tests for record Python bindings
  Add documentation for new instruction record Python bindings.
