This corrects a bug introduced with the addition of allowing loopback
and silent parameters in the init function.

94abf6e529 stm32/f1: Add user_reset_hook to reset_handler w/ jump_to_dfu preset

could be used for things like CRC checking of the firmware before boot

0834f41383 stm32f1:
Add object files to Makefile to include new modules into lib.

Correct typo in pwr.c

Add two new functions to timer.c to preset the counter (for use
with deadman style timeouts) and to identify an interrupt
source.

Also noticed lib/makefile.include didn't clean lib/stm32, which
isn't a target. Added a fix.

7d0611609b Code changes to stm32f1 adc.c and adc.h
remove rcc_set_adc_clk - use rcc version
Added functions:
 - adc_power_on
 - adc_start_conversion_direct
 - adc_set_dual_mode
 - adc_eoc
 - adc_eoc_injected
 - adc_read_regular
 - adc_read_injected
 - adc_set_injected_offset
Tested dual mode scanned regular, but no tests of injected yet.
Changes: "discontinuous" was misspelled.
 - adc_set_discontinuous_mode_regular - added "length" parameter
 - adc_disable_discontinuous_mode_regular - name change
 - adc_enable_discontinuous_mode_injected - name change
 - adc_enable_automatic_injected_group_conversion - disable triggers
 - adc_enable_jeoc_interrupt - name change to match common usage in lib
 - adc_disable_jeoc_interrupt - ditto
 - adc_enable_external_trigger_regular - remove incorrect test on parameter
 - adc_enable_external_trigger_injected - ditto
 - adc_set_sample_time - name change to match function's purpose
 - adc_set_conversion_time_on_all_channels - ditto
 - adc_set_injected_sequence - changed order of register loading (ref Barlow's issue)
 - adc_enable_analog_watchdog_on_all_channels - flipped AWDSGL
 - adc_enable_analog_watchdog_on_selected_channel - ditto
added aliases for expected commonly used functions to avoid sudden user code breakage

In adc.h, corrected errors in SQR names
added "deprecated" compiler warnings to adc_on and to aliases defined in adc.c

fc4047e4b4 Add assert macros to aid in debugging.
Adds libopencm3/cm3/assert.h header that provides assertion check macros
similar to those provided by the standard C library.

Thanks to Nicolas Schodet for help.

ff83a1ae1c Setup to document entire project using doxygen.
New doc directory with config files and generated html, LaTeX/pdf.
Makefile provided for autogeneration and explanatory README.

The project structure is hostile to doxygen, which can't cope with functions
of the same name. Doxygen is run for each family separately, and separately
for LaTeX generation. Customized layout files sort of "integrate" HTML, and
separate pdfs are generated for each family. Not ideal but seems the best
solution until doxygen changes, if at all.
