Enable EXPERIMENTAL support for pthread spinlocks.

This is marked EXPERIMENTAL for two reasons (1) the use case is not
|
||
|
|
fully verified, and (2) it depends on architecture specific
|
||
|
|
support provided by each architecture that may not be fully
|
||
|
|
available to the pthread library.
|
||
|
|
|
||
|
|
It also currently depends on CONFIG_BUILD_FLAT because the
|
||
|
|
critical test and set function (up_testset()) as prototyped in
|
||
|
|
include/nuttx/spinlock() does not permit an inline function or
|
||
|
|
macro to be used in user-mode application space.
