[PATCH v3 0/7] refactor the internals of record-full

[Guinevere Larsen <guinevere@redhat.com>]

This series introduces a refactor and modernization to the record-full
history, moving it form a manually managed doubly-linked list into an
std::deque, which can make better use of caching and might make
execution faster.

The main driving force behind this change is the plan to implement
support for multithreaded inferiors, since each instruction will need to
know the thread that executed it, and it'll be much easier if there is a
more consistent spot to find all this information.

Changes for v3: Made the former "cleanup" functions into actual
destructors. To do that and avoid double-frees, I made it so
record_full_entry (and the 2 classes under it) can't be copied, only
moved. Also implemented almost all the feedback from Christina on the
changes.

Guinevere Larsen (7):
  gdb/record: Refactor record history
  gdb/record: remove record_full_insn_num
  gdb/record: c++ify internal structures of record-full.c
  gdb/record: make record_full_history more c++-like
  gdb/record: extract the PC to record_full_instruction
  gdb/record: Define new version of the record-save section
  gdb/record: rename record_full_list to record_full_log
