Passing va_list in syscall does not work.  Temporarily moved syslog and lowsyslog into kernel code and access via a system call.  Need to revisit.  Will probably need to move all of syslog back from fs/syslog to libc/syslog

Misc changes to get a clean build after all of the syslog changes.  There are probably other things still broken

make standard syslog and vsyslog POSIX compliant (also modify non-standard syslog functions for compatibility).  This will break a lot of things until ALL usage of syslog is updated to use the modified interfaces

Update some Kconfig comments; Add a upper limit on the lower priority worker thread for priority inheritance

Remove non-functional vestiges of OTGHS in FS mode (including OTGFS2); try to convert the stm32f429i-disco configuration to use OTGHS instead of OTFHS in FS mode (OTGFS2).  But I don't have the boards and can't test

Integrates OTGHS support into the STM32; Eliminates the older OTGHS in FS mode logic.  From Brennan Ashton

Add files that implement true high speed support for the STM32 OTGHS peripheral.  From Brennan Ashton
