[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Usermode portion of the support for swap allocation accounting:
- update for getrlimit(2) manpage;
- support for setting RLIMIT_SWAP in login class;
- addition to the limits(1) and sh and csh limit-setting builtins;
- tuning(7) documentation on the sysctls controlling overcommit.

Add support for RLIMIT_NPTS to limits(1).

After the MPSAFE TTY import we support an additional rlimit, called
RLIMIT_NPTS. This limit allows you to cap the amount of pseudo-terminals
allocated by one user.

We forgot to add support for this limit to limits(1), which means it
crashed. Add the proper bits to make it work like it should.
Unfortunately not all shells actually implement the RLIMIT, so
unfortunately I suspect it to be broken with certain shells.

Significantly reduce the memory leak as noted in BUGS section for
setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.

Convert all calls to POSIX from historic BSD API:
- unsetenv returns an int.
- putenv takes a char * instead of const char *.
- putenv no longer makes a copy of the input string.
- errno is set appropriately for POSIX. Exceptions involve bad environ
variable and internal initialization code. These both set errno to
EFAULT.

Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit. A few I re-wrote to use setenv()
instead of putenv().

New regression module for tools/regression/environ to test these
functions. It also can be used to test the performance.

Bump __FreeBSD_version to 700050 due to API change.

Back out all POSIXified *env() changes.

Not because I admit they are technically wrong and not because of bug
reports (I receive nothing). But because I surprisingly meets so
strong opposition and resistance so lost any desire to continue that.

Anyone who interested in POSIX can dig out what changes and how
through cvs diffs.

limits calls setenv("name=value", "value", 1); which violates POSIX:
"The setenv( ) function shall fail if:
[EINVAL] The name argument is a null pointer, points to an empty string,
or points to a string containing an '=' character."
The fix (like all others in this subject) is backward-compatible.

Added the EXIT STATUS section where appropriate.

Use the accepted abbreviation "kB" for kilobyte, rather than "kb" (which
is the common unit for a kilobit).

This code builds cleanly at WARNS level 6.

Fix mdoc nits in preparation for RLIMIT_VMEM support:

* add missing Ar macro for one instance of limitflags

* fix indentation problem (not perfect, but then this is one _very_
awkward manpage mark up properly)

Use `The .Nm utility'

Warns cleanups:
1) Add missing initialisers.
2) Avoid shadowing rcswhich.
3) Use intmax_t and %j for printing rather than quad_t and %q.
4) Don't modify a variable twice between sequence points.

Don't use gcc specific flags.

Fixed some style bugs (bogus cloned Id, null overrides of defaults, and
the usual style bugs for DPADD/LDADD).

mdoc(7) police: replace -hang list with the -tag list,
add missing .Xo/.Xc to the tags. This only worked due
to the off-by-one bug in the -hang lists, which I will
hopefully backport from the mdocNG shortly.

mdoc(7) police: split punctuation characters + misc fixes.

mdoc(7) police: use the new features of the Nm macro.

Properly use .Nm, .Em, .Pa etc. Make usage() a simplier function.

This implements the RLIMIT_SBSIZE ("sbsize") administrative limits for
userland. Currently, it can be enforced by login and csh. More
shells supporting sbsize are welcome.
