[PATCH v3 00/24] accel/tcg: Restrict TCGCPUOps::cpu_exec_interrupt() to sysemu

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

[Series fully reviewed]

Hi,

The TCGCPUOps::cpu_exec_interrupt() handler is specific to system
emulation. This series remove it from user-mode.
To do so we have to deal with a x86-hack first, then we restrict
each target handler (one target at a time) and finally we restrict
the prototype, simplifying cpu_handle_interrupt().

As a bonus we can remove the cpu_get_pic_interrupt() stubs from
bsd/linux-user.

Since v2:
- Rebased due to bsd-user conflict (merge 99c44988d5b)
- Added R-b

Since v1:
- Addressed Richard comments (drop AVR patch, remove assert)
- Added R-b
