drivers/: Remove all explicit use of 'hidden' macro _info. Code must never use this directly. Code must always use a debug macro such as info which is basic on _info but can be appropriately filtered.

serial.c: Fix an error in FIONWRITE calculation

drivers/serial/pty.c, serial.c, usbdev/cdcacm.c, include/nuttx/fs/ioctl.h: Fix FIONWRITE and add FIONSPACE. All implementations of FIONWRITE were wrong. FIONWRITE should return the number of bytes waiting in the outgoing send queue, not the free space. Rather, FIONSPACE should return the free space in the send queue.

serial.c: Fix a race condition noted by Stefan Kolb. Between the test if the TX buffer is full and entering a critical section, bytes may be removed from the TX buffer making the wait unnecessary. The unnecessary wait is an inefficiency, but not really a problem. But with USB CDC/ACM it can be a problem because the entire TX buffer may be emptied when we lose the race. If that happens that uart_putxmitchar() can hang waiting for data to be removed from an empty TX buffer.
