and use per-process queue's for async requests. This makes ktrace more reliable and also fixes a potential deadlock in cv_wait/msleep.

Reuse ktr_unused field in ktr_header structure as ktr_tid; populate ktr_tid as part of gathering of ktr header data for new ktrace records. The continued use of intptr_t is required for file layout reasons, and cannot be changed to lwpid_t at this point. Reviewed by: davidxu Approved by: re (scottl)

Replace ktr_buffer pointer in struct ktr_header with a ktr_unused intptr_t. The buffer length needs to be written to disk as part of the trace log, but the kernel pointer for the buffer does not. Add a new ktr_buffer pointer to the kernel-only ktrace request structure to hold that pointer. This frees up an integer in the ktrace record format that can be used to hold the threadid, although older ktrace files will have a garbage ktr_buffer field (or more accurately, a kernel pointer value).
