Brian Behlendorf 1e33ac1e26 Fix Solaris thread dependency by using pthreads
This is a portability change which removes the dependence of the Solaris
thread library.  All locations where Solaris thread API was used before
have been replaced with equivilant Solaris kernel style thread calls.
In user space the kernel style threading API is implemented in term of
the portable pthreads library.  This includes all threads, mutexs,
condition variables, reader/writer locks, and taskqs.

Brian Behlendorf d6320ddb78 Fix gcc c90 compliance warnings
Fix non-c90 compliant code, for the most part these changes
simply deal with where a particular variable is declared.
Under c90 it must alway be done at the very start of a block.
