The f103 usb core should be usable on the l1 as well, and the /f1/rcc
isn't explicitly required anymore. This is an important change to be
able to share the driver.
The direct access definitions to the SHPR1 SHPR2 and SHPR3 were simply
wrong, and though a handy macro for directly reaching any priority field
was provided, the definitions of the fields assumed direct access to the
registers.
Provide field definitions that match the handy macro, and correct the
direct access definitions for people wishing to use them.
We currently default to "-mfloat-abi=hard -mfpu=fpv4-sp-d16" for M4F cores, and
and variations of "-mfloat-abi=soft" for the others. Keep the M4F default, and
move others to no FP flags for consistency, but allow overriding these flags
via the FP_FLAGS environment variable.

After a STALL handshake is transmitted, a control pipe becomes idle. Not
marking the pipe as idle did not affect the STM32 family. Since it
distinguishes between OUT and SETUP tokens, it calls the setup handler
on a SETUP token, regardless of the state of the pipe.
Other families, such as LM4F do not distinguish in software between IN and
SETUP tokens, and need to decide which handler to call based on the state
of the pipe. On these chips, SETUP transactions will not be handled
properly after a transfer was STALLED, as the state machine of the pipe is
b0rked. Unb0rk it.

Each thread runs its own stylecheck script, outputing to {FILENAME}.stylecheck file. If that file is empty, it is deleted. Otherwise it is printed to the output and stays in the sources directory to indicate something in that file is not correct.
The file mangling and cat-ing is needed because of multithreaded nature of paralell make. (We like single file to be an block of text on the output).
New PHONY added that make styleclean clears all .stylecheck files.
New functionality added to check only single file (specifyilng the file with stylecheck extension) ie
make lib/usb/usb.c.stylecheck
BUG: if someone edit that file, .stylecheck file is not regenerated - missing dependency on the %.stylecheck rule. FIX: make styleclean stylecheck rebuild all style errors
Performance:
make stylecheck 1:43 -> 1:54 (slightly slower due to file creation)
make stylecheck -j8 1:43 -> 0:34 (Rapidly faster)
note the -j option must be specified with number, OS Windows cannot handle one thread per file.
