This change adds a flag call TCB_FLAG_CUSTOM_STACK that may be passed in the the pre-allocated TCB to nxtask_init(). This flag is not used internally anywhere in the OS except that if set, it will prevent sched_releasetcb() from attempting to free that custom stack.

PR-1164 PR-1173 Implement some missing functions required for latest libc++

• aligned_alloc() posix_memaligned(), timespec_get(), wcsrtombs() wcsnrtombs(), mbsnrtowcs() mblen(), mbstowcs(), wcstombs()

PR-1172 Implement %ju and %jd printf formaters

PR-1179 Implement vscanf()

PR-1182 tmpfile() no longer hardcodes to /tmp path

PR-1186 printf() and vprintf() use buffered IO if available

PR-1174 Add support for mtx_timedlock recursive mutex

PR-1193 Add location directive to compiler.h to support location data in different memory sections

Bug Fixes

Many private architecture interfaces were using 'up_' instead of the arch name 'arm_'

...

This function requires traversing the VA_LIST twice.  For some architectures like x86 and x86_64 this needs to be cloned first.

Major Changes to the Build System

...

This removes support for the Codesourcery, Atollic, DevKitArm, Raisonance, and CodeRed toolchains. Not only are these tools old and no longer used but they are all equivalent to the standard ARM EABI toolchains. Retaining specific support has not meaningful (and they are still supported, but now just as generic EABI toolchains).

PR-1148 PR-1149 Improve build time especially on non-Linux platforms by providing a C version of incdir.sh

Bug Fixes

Many small changes to resolve dependency resolution issues that would sometimes appear during parallel builds.  Parallel builds should be much more reliable now and bugs filed against any issues found.

PR-1165 STM32H7: SPI transaction appears to be completed before the data has actually been flushed

TX DMA completes before the data has been actually sent out from the SPI fifo. This is expected, but the exchange should actually wait for spi tx to finish instead of dma to the fifo to finish. This replaces the dma completion event with the SPI TXC event for detecting end of transmission.
