Joerg Wunsch fae988778b 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.

* from: Onno van der Linden c/o frank@fwi.uva.nl
*
* Here's an idea how to automatically detect the version of NetBSD pcvt is
* being compiled on:
*
* NetBSD 0.8 : NetBSD0_8 defined in <sys/param.h>
* NetBSD 0.9 : NetBSD0_9 defined in <sys/param.h>
* NetBSD 1.0 : NetBSD1_0 defined as 1 in <sys/param.h>
* NetBSD 1.0A: NetBSD1_0 defined as 2 in <sys/param.h>
*
* The NetBSDx_y defines are mutual exclusive.
*
* This leads to something like this in pcvt_hdr.h (#elif is possible too):
*
*---------------------------------------------------------------------------*/
#ifdef NetBSD0_8
#define PCVT_NETBSD 8
#endif
#ifdef NetBSD0_9
#define PCVT_NETBSD 9
#endif
#ifdef NetBSD1_0
#if NetBSD1_0 > 1
#define PCVT_NETBSD 199
#else
#define PCVT_NETBSD 100
#endif
#endif
/*---------------------------------------------------------------------------
* Note that each of the options below should rather be overriden by the
* kernel config file instead of this .h file - this allows for different
* definitions in different kernels compiled at the same machine
*
* The convention is as follows:
*
* options "PCVT_FOO=1" - enables the option
* options "PCVT_FOO" - is a synonym for the above
* options "PCVT_FOO=0" - disables the option
*
* omitting an option defaults to what is shown below
*
* exceptions from this rule are i.e.:
*
* options "PCVT_NSCREENS=x"
* options "PCVT_SCANSET=x"
* options "PCVT_UPDATEFAST=x"
* options "PCVT_UPDATESLOW=x"
* options "PCVT_SYSBEEPF=x"
*
* which are always numeric!
