The addition of STM32_HAVE_TIMER() allows us to avoid some
repetition. There's still an issue with names on F1 preventing us from
moving the IRQ handlers to libmaple/timer.c, but once that's resolved,
we'll be able to remove even more.

The current versions of DELARE_*_TIMER() don't play well with cscope,
which is a bad sign. Fix that.

Fix @file in many places. Also fix up the descriptions where it's
appropriate. This standardizes the @file formatting across the library
to explicitly include any parent directories up to the repository
root.
Besides being nice, this will hopefully let us manage Doxygen's XML
output so as to make extracting series-specific pieces via Breathe in
the leaflabs-docs repo possible.

This applies to XL-density STM32F1 devices.
In stm32f1/timer.c, add timer_dev's for the new timers, using the
timer_private API. These definitions are conditionally compiled based
on the target density to avoid wasting space on smaller MCUs. Also add
calls to the appropriate timer_private.h dispatch routines within the
IRQ handlers for these timers. We need to change the IRQ handler names
to reflect this eventually, but put that off for now, as it could
break backwards compatibility in some exotic situations where the user
refers to the libmaple IRQ handlers directly.
In stm32f1/timer.h, add register map base pointers and device
declarations for the new timers. timer_dev* declarations are compiled
in only when the target MCU supports them, in keeping with the above
stm32f1/timer.c changes.
In libmaple/timer.c, update the (static) IRQ enable routines to
account for the additional timers. This adds some code that's
unnecessary on smaller STM32F1s, but it's minimal (40 extra bytes on
my machine), so portability and readability win out.
Size change, using GCC version "(Sourcery G++ Lite 2011.03-42) 4.5.2":
Before:
text data bss dec hex filename
615 0 0 615 267 build/home/mbolivar/leaf/libmaple/libmaple/timer.o
After:
text data bss dec hex filename
655 0 0 655 28f build/home/mbolivar/leaf/libmaple/libmaple/timer.o

Fix copy-paste errors in, and add missing, register bit
definitions. For copy-paste errors that would result in source
incompatibilities with past releases, add some legacy defines.
Add series header and C file for STM32F1 which fills in the missing
API. Much of the F1 timer.c would be repeated on F2, so also add
timer_private.h to hold these.
Support for timers 9 through 14 is still missing.
