Commit f752b46e added the cv_wait_interruptible() function to allow
condition variables to be woken by signals. This function and its
timed wait counterpart should have been named cv_wait_sig() to match
the illumos interface which provides the same functionality.
This patch renames the symbol but leaves a #define compatibility
wrapper in place until the ZFS code can be moved to the correct
name.
This patch also makes a small number of cosmetic changes to make
the condvar source and header cstyle clean.
