Read TIMx_SR before grabbing a pointer to the user handlers instead of
after. This should shave a couple of cycles off of the time between
IRQ entry and SR read.

Remove dispatch_irq() and dispatch_cc_irqs().
For IRQs which handle exactly one timer interrupt, add new
dispatch_single_irq(). The mere fact that the IRQ has been called
suffices to prove that its interrupt enable bit (in TIMx_DIER) and
interrupt flag (in TIMx_SR) are set. These facts are combined in
dispatch_single_irq(), which only needs to check if the timer_dev
handler is non-null before calling it and clearing the SR flag.
For IRQs which serve multiple timer interrupts, replace the
composition of calls to dispatch_irq() and dispatch_cc_irqs() with
individualized routines. These eliminate unnecessary timer register
reads/writes, and, in the case of capture/compare interrupts, have a
loop unrolling performed.

Modify them to check whether the relevant interrupts are enabled
before attempting to handle them.

Various names in timer.h were too unwieldy. Making these slightly
more bearable.

From declaration to definition, to keep with convention.

Added an adc_dev to struct stm32_pin_info. This was necessary to add
support for the channels on the Native which are only connected to
ADC3, but it does add a bunch of NULLs to the PIN_MAPs.
I don't think any other peripherals need representation on a per-pin
basis. Each peripheral library will be responsible for keeping track
of related GPIO ports and bits, and we can throw #defines in to
boards/*.h for other things (e.g. BOARD_SPI1_MISO_PIN).
Fleshed out the ADC refactor and brought it more in keeping with the
new design as it evolves.
A couple of other tweaks. Notably: waitForButtonPress() now takes a
default argument meaning "wait forever".
Removed Maple-specific documentation from core functions in io.h; this
information will need to go into the individual board docs files.

Basic PWM works. Had some problems in testing that might be due to
USART bugs.
HardwareTimer has been removed from the build for now; I will
re-implement it in terms of the new libmaple API, but consider it
deprecated. Let's come up with something better.
Servo is implemented in terms of HardwareTimer, so it also has been
temporarily removed from the build.
pwmWrite() likely got a little bit less inefficient due to
indirection, but the PIN_MAPs shrank by a pointer per PinMapping.
