[PATCH 0/6] Don't throw quit while handling inferior events

[Pedro Alves <pedro@palves.net>]

This series implements what I suggested here:

  https://inbox.sourceware.org/gdb-patches/ab97c553-f406-b094-cdf3-ba031fdea925@palves.net/

... and then some more.

To expose the problem with a testcase, I added a new $_shell
convenience function, and I'm using that to send a SIGINT signal to
GDB from a breakpoint condition.

While writing tests for the new $_shell convenience function, I ran
into a number of bugs, also fixed in the series.

Pedro Alves (6):
  Fix "ptype INTERNAL_FUNC" (PR gdb/30105)
  Make "ptype INTERNAL_FUNCTION" in Ada print like other languages
  Add new "$_shell(CMD)" internal function
  Don't throw quit while handling inferior events
  GC get_active_ext_lang
  Don't throw quit while handling inferior events, part II
