coda.h:
- CodaFid typdef -> struct CodaFid throughout.
- Use unsigned int instead of unsigned long for venus_dirent and other
cosmetic fixes.
- Introduce cuid_t and cgid_t and use instead of uid_t and gid_t in RPCs.
- Synchronize comments and macros.
- Use u_int32_t instead of unsigned long for coda_out_hdr.
With these changes, a 64-bit Coda kernel module now works with
coda6_client, whereas previous userspace and kernel versions of RPCs
differed sufficiently to prevent using the file system. This has been
verified only with casual testing, but /coda is now usable for at least
basic operations on amd64.

This makes sh a bit more friendly in single user mode, make buildenv, chroot
and the like, and matches other shells.
The -o emacs can be overridden on the command line or in the ENV file.
This fix mostly matters after r206129 that made it possible for
st_blksize to be greater than 4K. For this reason, this change should
be MFC-ed before r206129.
Also, it seems that all FreeBSD uitlities that use db(3) hash databases
and create new databases in files, specify their own block size value
and thus do not depend on block size autotuning.

in the readdir functions for non-positive byte count arguments.
For the negative case, set it to the maximum allowable, since it
was actually a large positive value (unsigned) on the wire.
Also, fix up the readdir function comment a bit.

Note that the following sentence

is now true, but used to be incorrect.
This applies to word in ${v-word}, ${v+word}, ${v=word}, ${v?word} (which
inherits quoting from the outside) and in ${v%word}, ${v%%word}, ${v#word},
${v##word} (which does not inherit any quoting).
In all cases tilde expansion is only attempted at the start of word, even if
word contains spaces. This agrees with POSIX and other shells.
This is the last part of the patch tested in the exp-run.

Note that this depends on r206145 for allowing pattern match characters to

* remove the backslash from \} inside double quotes inside +-=?
substitutions, e.g. "${$+\}a}"
* maintain separate double-quote state for ${v#...} and ${v%...};
single and double quotes are special inside, even in a double-quoted
string or here document
* keep track of correct order of substitutions and arithmetic
This is different from dash's approach, which does not track individual
double quotes in the parser, trying to fix this up during expansion.
This treats single quotes inside "${v#...}" incorrectly, however.
This is similar to NetBSD's approach (as submitted in PR bin/57554), but
recognizes the difference between +-=? and #% substitutions hinted at in
POSIX and is more refined for arithmetic expansion and here documents.

The old approach was wrong because PS2 was not used and seems unlikely to

In other words, deny multiple read-only mounts of the same device.
Shared read-only mounts should theoretically be possible, but,
unfortunately, can not be implemented correctly using current
buffer cache code/interface and results in an eventual system crash.
Also, using nullfs seems to be a more efficient way to achieve the same
goal.
This gets us back to where we were before GEOM and where other BSDs are.

As currently st_blksize is always PAGE_SIZE, it is playing safe to not
use any smaller value. For some cases this might not be optimal, but
at least nothing should get broken.
Generally I don't expect this commit to change much for the following
reasons (in case of VREG, VDIR):
- application I/O and physical I/O are sufficiently decoupled by
filesystem code, buffer cache code, cluster and read-ahead logic
- not all applications use st_blksize as a hint, some use f_iosize, some
use fixed block sizes
I expect writes to the middle of files on ZFS to benefit the most from
this change.
