For Bug 543:
...
Standardize the error messages to be in "path: what failed: why" format.
Also attempt to use the correct errno to ThrowErrno in situations where
the errno value is erased by subsequent system calls.

For Bug 543:
...
Allow the ThrowErrno function to optionally accept an error number
parameter so that callers can specify the error number to be used.
