c50897c392 Put back the openpty(3) and ptsname(3) fixes but don't disable ptsname(3) 
on pts(4) devices this time.  This fixes the issues while leaving pts(4)
enabled on HEAD.

d3f576839b Back out last commit, since it accidentally broke pts. 
The security fix will be re-committed soon, hopefully without breaking
anything.

16fd04e88e Update the manpage for openpty(3) to account for the recent fixes. 
Specifically, remove the BUGS section and note that openpty(3) now always
does the various security-related steps.  Also, update the error return
value section.  The PR below is for the original bug rather than the doc
updates.

889befc455 Invoke revoke(2) on the slave pty in the pts(4) case (new_openpty()) to 
kick off any other users on the device line before using it since
openpty(3) is documented to do this.  Note that grantpt(3) does not
call revoke(2), it only adjusts permissions and ownership.

fefc6803cf When pidfile is already locked and has zero length, do not return 
success and zero pid from pidfile_read(). Return EAGAIN instead. Sleep
up to three times for 5 ms while waiting for pidfile to be written.

mount(8) does the kill(mountpid, SIGHUP). If mountd pidfile is truncated,
that would result in the SIGHUP delivered to the mount' process group
instead of the mountd.

- While here, check the unit before calculating the actually number.

bd35b57de2 Implement expand_number(3), which is the opposite of humanize_number(3), ie. 
a number in human-readable form is converted to int64_t, for example:
123b -> 123
10k -> 10240
16G -> 17179869184

b31d5b56ec strlcpy() may be faster than snprintf(), but it is less portable, and this 
is not performance critical code anyway.  Also, avoid using strlen() to
obtain information which we already have.
