gold linker v2.22: Fix constructor handling

Starting with gold 2.22, gold looks for contructors in DT_INIT_ARRAY by

presence of crtbegin and crtend with their .init sections are confusing
gold, but not gnu ld.

To combat this, a new option "--no-ctors-in-init-array" was added to
emulate gnu ld behavior of looking for constructors in the .ctors
section provided by gcc.  This commit makes this new option the default
behavior on DragonFly's gold.

kernel -- Per-mount syncer thread infrastructure.

Introduce infrastructure to create per-mount periodic filesystem syncer threads.

For a filesystem flagged MNTK_THR_SYNC, create a thread to periodically
synchronize dirty vnodes and the entire filesystem via VOP_FSYNC and
VFS_SYNC. This thread subsumes that responsibility from the global syncer.
The thread will be created at mount time and torn down at unmount.

For filesystems not flagged, the global syncer thread (syncer0) is still used.
The global syncer thread is also used for the bioops_sync(NULL) call, to
invoke every filesystem's bioops_sync path. This is primarily a concern for
UFS/softdep. The global syncer is also the only syncer thread to respond to
speedup_syncer / rushjob requests; this is again a consideration for softdep.
