0a2a08739e libfsdriver: clear VM cache only if used
As part of its built-in mmap emulation support for "none" file system
services, libfsdriver clears the VM cache upon exit.  However, for
trivial file systems which do not even support reading from files, the
the VM cache need to be cleared either.  With this patch, the VM cache
is cleared only when modified, so that such trivial file systems need
not be given CLEARCACHE permission.

3f30eb69f0 libfsdriver: default to noop for putnode
While putnode requests should always succeed, very simple file system
services may not care about reference counts and thus about putnode
requests at all.  For this reason, we now default to an OK response if
no fdr_putnode implementation is given.

22840dea11 libfsdriver: preinitialize stat.st_ino
The stat.st_ino field must always be filled with the inode number
given as part of the fdr_stat request anyway, so libfsdriver can
simply fill in the number and allow the file system not to bother.

5055c7ea51 VFS: fix pipe resumption delay bug
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.

af4345b097 isofs: do not link against libc
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).

dfc3261535 PFS, inet: use static UID to drop privileges
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.

7eb698ea4a VFS: during initial mount, receive but block work
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.

179bddcf5d VFS: fix error behavior for partial pipe writes
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.

79444d163d mined: increase the size of the tgetent() buffer.
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.)"

d131b58784 mined1.c: remove i386 guard around escape sequences.
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.
