[PATCH nbdkit] server: Use GCC hints to move debug and error handling code out of hot paths.
For GCC only, define unlikely() macro. Use it on error paths to move
code out of the hot path.
In the server only, use the debug() macro (don't call nbdkit_debug
directly). This macro checks the verbose flag and moves the call to
nbdkit_debug out of the hot path.
