cfd91eac07 Rearrange context saving. 
Variables are now associated with the module that declares them, being
initialised and saved/restored there.  However, as many variables are
used for communication between modules, many of them are set in multiple
places, so the assignment is ambiguous.

c0d01a6fe0 Fix command substitutions to parse contents as they are read in. 
Do this by refactoring misnamed lexsave()/lexrestore() to allow
continuity of history and input.

Add test.

18b60d8512 34117: zle: size_t is unsigned, use int instead 
The function wctomb returns an int according to my manpage, and we
furthermore check if it is negative, and then return it, and the function
signature is int, so declaring it as an int seems to make more sense.

d067ebcacd 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.
