sys/sys: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Merge r242395,242483 from mutex implementation: give rwlock(9) the ability to crunch different type of structures, with the only constraint that they have a lock cookie named rw_lock. This name, then, becames reserved from the struct that wants to use the rwlock(9) KPI and other locking primitives cannot reuse it for their members. Namely such structs are the current struct rwlock and the new struct rwlock_padalign. The new structure will define an object which has the same layout of a struct rwlock but will be allocated in areas aligned to the cache line size and will be as big as a cache line. For further details check comments on above mentioned revisions. Reviewed by: jimharris, jeff

- Embed the recursion counter for any locking primitive directly in the lock_object, using an unified field called lo_data. - Replace lo_type usage with the w_name usage and at init time pass the lock "type" directly to witness_init() from the parent lock init function. Handle delayed initialization before than witness_initialize() is called through the witness_pendhelp structure. - Axe out LO_ENROLLPEND as it is not really needed. The case where the mutex init delayed wants to be destroyed can't happen because witness_destroy() checks for witness_cold and panic in case. - In enroll(), if we cannot allocate a new object from the freelist, notify that to userspace through a printf(). - Modify the depart function in order to return nothing as in the current CVS version it always returns true and adjust callers accordingly. - Fix the witness_addgraph() argument name prototype. - Remove unuseful code from itismychild(). This commit leads to a shrinked struct lock_object and so smaller locks, in particular on amd64 where 2 uintptr_t (16 bytes per-primitive) are gained. Reviewed by: jhb

Introduce a new rwlocks initialization function: rw_init_flags. This is very similar to sx_init_flags: it initializes the rwlock using special flags passed as third argument (RW_DUPOK, RW_NOPROFILE, RW_NOWITNESS, RW_QUIET, RW_RECURSE). Among these, the most important new feature is probabilly that rwlocks can be acquired recursively now (for both shared and exclusive paths). Because of the recursion counter, the ABI is changed.
