ac36cf2d4b In closefrom_fallback() use the interval [OPEN_MAX, INT_MAX].
We want to try closing at least OPEN_MAX fds but no more than INT_MAX.
On 64-bit systems it is possible for sysconf(_SC_OPEN_MAX) to return
a value larger than INT_MAX when the number of open files is unlimited.

e80079eaa8 Set resource limits in the sudo process to unlimited.
We don't want sudo to be limited by the caller's resource limits.
The original resource limits are restore before session setup.

3e56be3564 Store signal name, not number in I/O log timing file.
The "SIG" prefix is not used so, e.g. SIGTERM -> "TERM".
This makes the I/O log files portable from one system to another.
Older I/O log files with signal numbers can still be replayed.

9d8f374397 Add ssizeof macro that returns ssize_t.
We can use this instead of casting the result of size_t to int.
Also change checks for snprintf() returning <=0 to <0.

17ca31c381 Ignore EOVERFLOW from pstat_getproc(), it is not a fatal error.
It just means that one of the fields in pstat lacks the precision to
store a value.  That's not an issue for pst_highestfd.

985600e7f0 Minor snprintf() usage tweaks:
1) don't assume snprintf() returns -1 on error, check for <0
2) when comparing return value of sizeof(foo), cast the sizeof, not the len
3) cast return value to void in cases where snprintf cannot fail

f7d7a9a619 Fix the default nofiles and stack hard limits.
The table of default hard limits in /etc/security/limits was out
of date with respect to the current documentation.  The default
hard limit for nofiles should be unlimited, not 8196.  The default
hard limit for stack should be 4194304 blocks (which fits in an
unsigned long on 32-bit platforms).
