Make exti_get_flag_status and exti_reset_request use EXTI_RPR and EXTI_FPR if present instead of EXTI_PR.
This is less precise than offered by the RPR/FPR registers, but makes
for a consistent experience in the common API.

EXTICR on stm32g0 is in exti registers range. Previous chips used to have that
gpio port exti mux configuration accessible via AFIO_EXTICR or SYSCFG_EXTICR.
Also, the new chip now use 8 bits coded value instead of previously 4 for the
extcr mux selection value (see AFIO/SYSCFG/EXTI_EXTICR_FIELDSIZE)
Let's define two helpers: EXTICR_SELECTION_REG (to get proper AFIO/SYSCFG/
EXTI_EXTICR register) and EXTICR_SELECTION_FIELDSIZE (to get proper AFIO/SYSCFG/
EXTI_EXTICR_FIELDSIZE value), and use it them exti_select_source to determine
exticr mux selection bits shift and mask.
to remove variations, redundancies, add missing, fix errors. All c files
refer only to the dispatch style headers in /include/stm32. Those headers
#include memorymap.h and cm3/common.h. All references to
these are removed from the family specific headers. Ethernet untouched as
it appears incomplete.
Added dummy spi.c for F0/F3. Fix some doxygen anomalies.
So that the navigation pane works correctly in browsers.
Some additional doc fixes put in where found (but many more still to go).
Added some dummy .c and .h files to bring the associated docs into line.
makefile changed to allow 'make html' as well as 'make doc' (the latter only does html anyway).
