Rather than continuing to propagate try/catch (Closed)
(aka LLThreadSafeQueueInterrupt) constructs through the code base, make
WorkQueueBase::post() return bool indicating success (i.e. ! isClosed()).
This obviates postIfOpen(), which no one was using anyway.
In effect, postIfOpen() is renamed post(), bypassing the exception when
isClosed().
Review existing try/catch blocks of that sort, changing to test for post()
returning false.
Remove all references to LLQueuedThread (but emulate a couple bits of its API
such as handle_t and getPending()).
Migrate ImageRequest into llimageworker.cpp. It has never been part of
LLImageDecodeThread's public API. Remove ImageRequest tests.
Remove all references to LLImageDecodeThread::pause(). The idea of pausing
another thread is bizarre to me, and LLThreadPool has no such operation. Nor
does it have an abortRequest().
this is a combined mergeback of the following branches as per QAR-841:
