[libdispatch-dev] Solaris portability - PATCH - fundamental libdispatch test suite patch

Hi,
Attached is the patches required to be able to build the fundamental portable test suite of libdispatch on Solaris after the previous getprogname patch has been applied using libkqueue.
The attached shim source files for arc4random/fgetln/asprintf were fundamentally based of previous open sources from opensource.apple.com - URL reference provided at the top of each.
I hope it was stylistically ok to add the shims to libtest_la_SOURCES.
With this, the following tests are operational (though not always successful…) on Solaris:
./dispatch_api
./dispatch_c99
./dispatch_cascade
./dispatch_debug
./dispatch_priority
./dispatch_priority2
./dispatch_starfish
./queue_finalizer
Cheers,
Joakim
