Fix many long-standing bugs and problems with pcvt, namely:

. make pccncheck() work even when interrupts are disabled, so the
  ``Press a key on the console...'' procedure will work,
. make kernel colors #ifndef, so they can be overridden from the
  config file,
. use shutdown_nice() instead of cpu_reset() if Ctrl-Alt-Del is
  enabled,
. allow pccngetc() to return more than a single character, so the
  arrow keys will work (and thus visual UserConfig!),
. fix a warning.

This closes all know PRs related to pcvt, in particular #845, #1236,
and #1265.  PR #991 is a duplicate for 845, and PR #1283 has already
been fixed earlier in rev 1.11 of pcvt_conf.h.
