Commit 723e513 erroneously removed a yield() call from VFS which was
necessary to get resumed pipe read/write threads to run before VFS
blocks on receive(). The removal caused those threads to run only
once VFS received another message, effectively slowing down activity
on pipes to a crawl in some cases.
Instead of readding the yield() call, this patch restructures the
get_work() code to go back through the main message loop even when no
new work is received, thus ensuring that newly started threads are
always activated without requiring a special case.
This fixes#65.

kb_init() panics, if no keyboard controller is found during self-test.
Instead of panic, the driver should quit the init process and tell it the SEF .

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.

The escape sequences for the function keys used to be separated
out in older versions of Minix when they were different for m68k
and intel. Support for m68k was dropped and that code was
removed, leaving the ifdef i386. Since the sequences are the
same for i386 and arm, there is no need to keep the ifdef i386.

Seems like its a kind of convention introduced by Intel but not
mandatory from a PCI specification point of view, that the PCI host
controller resides on bus 0, device 0 function 0. At least tinybios
(the bios used by ALIX and WRAP) based appliances are not able to boot
with this change.
