Simplify tdeletechar and tinsertblank and fix memory corruption.

Current CSI parsing code uses strtol to parse arguments and allows them
to be negative. Negative argument is not properly handled in tdeletechar
and tinsertblank and results in memory corruption in memmove.

Reproduce with printf '\e[-500@'

Patch also removes special handling for corner case and simplifies
the code.

Removed
term.dirty[term.c.y] = 1
because tclearregion sets dirty flag.
