- Reconnect with some minor modifications, in particular now selsocket()
internals are adapted to use sbintime units after recent'ish calloutng
switch.
In BSD, fgetln() available in libc but in Illumos the Solaris port had to
include it internally. It also seems to have caused problems [1].
Aid portability by using getline() instead.

This is actually a fully functional build except:
* All internal shared libraries are static linked to make sure there
is no interference with ports (and to reduce build time).
* It does not have the python/perl/etc plugin or API support.
* By default, it installs as "svnlite" rather than "svn".
* If WITH_SVN added in make.conf, you get "svn".
* If WITHOUT_SVNLITE is in make.conf, this is completely disabled.
To be absolutely clear, this is not intended for any use other than
checking out freebsd source and committing, like we once did with cvs.
It should be usable for small scale local repositories that don't
need the python/perl plugin architecture.
This checks that every node that has children specifies their register sizes.
This is not enabled by default, as the default sizes are sometimes required
(including by some DTS in the tree), but can help when writing new device
trees so that you can check that you actually meant the defaults.
Explicitly use GNU cpp for preprocessing.
Remove explicit debugging code.
Change some variable names to be less confusing.
Improve some comments.
Improve indentation.

The option tells kdump to convert numeric UIDs and GIDs into user and
group names plus to convert times and dates into locallized versions.
This all needs opening various files at various occasions.
Make use of Capsicum to protect kdump(1), as it might be used to parse data
from untrusted sources:
- Sandbox kdump(1) using capability mode.
- Limit stdin descriptor (where opened file is moved to) to only
CAP_READ and CAP_FSTAT rights.
- Limit stdout descriptor to only CAP_WRITE, CAP_FSTAT and CAP_IOCTL.
Plus limit allowed ioctls to TIOCGETA only, which is needed for
isatty() to work.
- Limit stderr descriptor to only CAP_WRITE and CAP_FSTAT. In addition
if the -s option is not given, grant CAP_IOCTL right, but allow for
TIOCGWINSZ ioctl only, as we need screen width to dump the data.
- Before entering capability mode call catopen("libc", NL_CAT_LOCALE),
which opens message catalogs and caches data, so that strerror(3)
and strsignal(3) can work in a sandbox.

Rearrange the code so we don't call ioctl(TIOCGWINSZ) if the -s option is given,
as the result won't be used then.

fclose() being skipped. Fix this by using boolean "&" and "|" instead of
short-cut operators "&&" and "||".
While here, increment the last part of the version string. The reason is

Instead of using the file with the least order of path name components,
shortest filename and finally the shortest basename (with the search
stopping as soon as one of these conditions is true), the first filename
checked was used as the reference, and another filename was only selected
if all of the above comparisons are in favour of the latter file.
This was wrong, because filenames with path less components were only
considered, if both of the other conditions were true as well. In fact,
the first filename to be checked had good chances to be selected in the
end, since it only needed to be better with regard to any one of the
three criteria ...

kernel-based POSIX semaphore descriptors to userland via procstat(1) and
fstat(1):
- Change sem file descriptors to track the pathname they are associated
with and add a ksem_info() method to copy the path out to a
caller-supplied buffer.
- Use the fo_stat() method of shared memory objects and ksem_info() to
export the path, mode, and value of a semaphore via struct kinfo_file.
- Add a struct semstat to the libprocstat(3) interface along with a
procstat_get_sem_info() to export the mode and value of a semaphore.
- Teach fstat about semaphores and to display their path, mode, and value.

This compiler flag enforces that that people either mark variables
static or use an external declarations for the variable, similar to how
-Wmissing-prototypes works for functions.
Due to the fact that Yacc/Lex generate code that cannot trivially be
changed to not warn because of this (lots of yy* variables), add a
NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this
specific compiler warning.

- Casting to long double isn't needed.
- The division isn't needed, multiplication can be used.
"When 1 nanosecond is in a floating point literal, the whole
expression is automatically promoted correctly."
- non-KNF indentation (1 tab) for the newly split line
- different non-KNF indentation (5 spaces) for the previously split
line
- exessive parentheses around the division operation
- bogus blank line which splits up the etime initialization
- general verboseness from the above.
