libpthread/nptl: make default stack size configurable
Threads currently have 2-4 MiB stacks by default (depending on the platform). This is fine on MMU platforms, where this stack space is not actually allocated until it is used, but tends to waste a large amount of memory on no-MMU platforms. This patch adds a PTHREADS_STACK_DEFAULT_SIZE Kconfig option that allows the user to override the default stack size at build time. This allows the user to select a reasonable default stack size for the software that runs on their system, and avoids the need to patch every package to add calls to pthread_attr_setstacksize(). An alternative to this patch would be to change the hardcoded default stack size on no-MMU platforms, but it is difficult to choose an appropriate value because the minimum required stack depends on the software in use. This would also be a breaking change. Signed-off-by: Ben Wolsieffer <ben.wolsieffer@hefring.com>
