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.

So now one can run procstat(1) on a process core e.g. to get a list of
files opened by a process when it crashed:

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.

An MFC is planned once the actual 3.3 release is finished.
happens if another atrm process removes a job while we're scanning through
the directory.
- While at it, optimize a bit the directory scanning, so that we quit looping
as soon as all jobs specified in argv have been dealt with.

pointed out by bde:
- 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.
