sched/clock: Move the implementation of clock() from libs/libc/time to sched/clock. This is necessary because it calls the (now) internal OS function clock_systimer. clock() is now accessed only via a system call in certain configuratins.
libs/libc/wqueue: Replace calls to clock_systimer() with calls to the equivalent clock().
Squashed commit of the following:
sched: Rename all use of system_t to clock_t.
syscall: Rename all use of system_t to clock_t.
net: Rename all use of system_t to clock_t.
libs: Rename all use of system_t to clock_t.
fs: Rename all use of system_t to clock_t.
drivers: Rename all use of system_t to clock_t.
arch: Rename all use of system_t to clock_t.
include: Remove definition of systime_t; rename all use of system_t to clock_t.

stm32f7: serial: Fix ioctl TIOCSSINGLEWIRE
The TRM notes that UE must be disabled in order to write HDSEL in
USART_CR3. This was not being done, so calls to TIOCSSINGLEWIRE were
silently failing.
This change checks the state of UE in USART_CR1, clears the UE bit
before writing HDSEL, then re-enables it if neccesary.

drivers/xbee: Fixes issue with timeouts. Timeouts were in ticks but should have been in ms. This caused false triggers of timeout causing redundant packets, etc.

* stm32f429i-disco: Fixes eliminated register control by compiler optimization
When reading 1 byte from the SPI device the clock must be enabled and
immediately disabled. This section has been optimized by the compiler (-O2) to a
missing active spi clock. A subsequently block read failed because of missing
response from the spi device. This has been lead to a broken display
initializing.

Signal handlers maybe run with interrupts enabled or disabled, depending on how the task the received the signal was blocked. (i.e.: If sem_wait() is called, then we disable interrupts, then block the currently running task). This could be dangerous, because user code would be running with interrupts disabled.
This change forces interrupts to be enabled in up_sigdeliver() before executing the signal handler calling up_irq_enable() explicitly. This is safe because, when we return to normal execution, interrupts will be restored to their previous state when the signal handler returns.
