This change requires a small patch to libc, in order to avoid that
libminc has to pull in a large chunk of libc just for mktime(3).

Previously, services would obtain the user ID of "service" through
getpwnam(3). While this approach is conceptually better, it also
imposes linking against libc which in turn causes problems with
printf(3), which already led to PFS no longer dropping privileges at
all. For now, we hardcode SERVICE_UID and use that instead.
In the future, two changes should allow removal of SERVICE_UID again:
- "service edit" should cause RS to request that a service (such as
PFS) drop privileges through SEF, using the user ID resolved by
service(8), or something similar;
- a future devfs should make it possible for inet to start without
root privileges altogether.

For VFS, initialization is a special case for processing work: PFS
and the ramdisk MFS must be fully mounted before VFS can process any
other requests, in particular from init(8). This case was handled by
receiving reply messages only from the FS service being mounted, but
this effectively disallowed PFS from calling setuid(2) at startup.
This patch lets VFS receive all messages during the mounting process,
but defer processing any new requests. As a result, the FS services
have a bit more freedom in what they can do during startup.

This patch fixes two related issues:
- If a large (>PIPE_BUF) pipe write is processed partially, only to be
followed by a write error condition, then the process is left in an
incorrect state, possibly causing VFS to crash on a subsequent call.
- If such a partially processed large pipe write ends up resulting in
an EPIPE error, no corresponding SIGPIPE signal is generated.
The corrected behavior is tested in test68.

From the termcap section of the GNU termutils manual:
"There is no way you can tell how much space is needed, so the convention
is to allocate a buffer 2048 characters long and assume that is enough.
(Formerly the convention was to allocate 1024 characters and assume that
was enough. But one day, for one kind of terminal, that was not
enough.)"

__STDC__ is used to mitigate the differences between K&R C and the
ANSI C standard. Nearly every compiler now supports ANSI C, so
there is no need to support non-standard compilers.

* Remove undef NULL, EOF, getchar, putchar
* Rename putchar, getchar, _putchar, _getchar to putch, getch, _putch,
_getch to avoid conflict with libc functions.
* Rename UP() to UP1() (for UP 1 line) to avoid conflict with UP
definition in termcap.h. Rename DN1 LF1 RT1 for consistency.
* Add termcap.h for prototypes for tputs and friends.
* Add libterminfo references to Makefile
* Add return value to _putch() to make it work as tputs expects.
* Make putch() call _putch()
* Remove UNIX ifdefs and all code in the !UNIX branches.

Removes the following man pages:
* awk.1x -- for a version of awk we no longer have
* kermit.1x -- seems gone altogether
* macros.1x -- not useful for anyone anymore
Moves the following man pages:
* mined.1x -- Moved to minix/commands/mined/mined.1
and reformatted to use the mdoc macros instead of the
Minix macros so that it displays properly.
Removes /usr/man/man1x from the directory tree.
