33876: etc.: Separate errors and keyboards interrupts
Combination of 12 commits from interrupt_abort branch.
Basic strategy is to introduce bits to errflag and to set and
reset them separately.
Remove interrupt status on return to main keymap.
Turn off ERRFLAG_INT for always block.
Restore bit thereafter: we probably need a new variable in order
to allow user interrupts to be reset in the always block.
Add TRY_BLOCK_INTERRUPT
This works the same as TRY_BLOCK_ERROR, but for a SIGINT, too.
Ensure propagation of SIGINT from exited job.
If received by foreground job, shell uses ERRFLAG_INT, not
ERRFLAG_ERROR, to set the new state.
Reset errflag before precmd()
Add always block in _main_completion to fix ZLS_COLORS
Ensures we get the right state of $ZLS_COLORS at the end of _main_complete
even if there's an interrupt. However, the "right state" is a bit messy
as it depends on styles.
