Note that HTTPTimeout::sClockWidth is no longer used for HTTPTimeout (as
if it's value became a constant of 0.01, the fraction 10ms / 1s).
A new variable, HTTPTimeout::sClockWidth_10ms is used to calculate
sTime_10ms (only).
Also HTTPTimeout::mStalled and HTTPTimeout::mLowSpeedClock changed units
to the same as of sTime_10ms (time since epoch in 10ms units).
This fixes a bug where unref() was called when a state machine was
aborted before it reached bs_initialized. Debug code was added to detect
errors related to that.
In order to run HTTPGetResponder in any thread, I needed direct access
to LLHTTPClient::request, so I had to move that to the header file,
and therefore had to move ERequestAction from LLURLRequest to
LLHTTPClient to avoid include problems.
With this, textures are fetched with no latency: call to
LLHTTPClient::request runs all the way till the state machine is idle
(AICurlEasyRequestStateMachine_waitAdded). There is small delay till the
curl thread wakes up, which then processes the request and opens the url
etc. When the transaction is finished, it calls
AIStateMachine::advance_state(AICurlEasyRequestStateMachine_removed_after_finished)
which subsequently doesn't return until the state machine is completely
finished (bs_killed). The LLURLRequest isn't deleted yet at that point
because the AITimer of the LLURLRequest runs in the main thread: it is
aborted, but only the next time the main thread state engines run that
is deleted and the timer keeps an LLPointer to it's parent, the
LLURLRequest, so only then the LLURLRequest object is destructed. This
however has nothing to do with the texture-bandwidth loop.
This class can be used as RWLOCK parameter to AIThreadSafe to check that
data is only accessed by a single thread (like
AIThreadSafeSingleThreaded) AND is never write locked when a read or
write lock was already obtained (by the same thread). It doesn't
actually lock anything, it just keeps track if the "lock" was obtained
before. The use case is to check if STL containers aren't being used
(read or write locked) by a calling function when additional write
access is necessary, as write access might invalidate iterator that
point to the container (where the previous lock was taken).
This allows passing a different type than the default AIRWLock for
debugging purposes.
The signature of the class used for RWLOCK should be:
struct RWLock {
// Default constructor.
RWLock(void);
// Block until it's safe to read the data.
// high_priority is a hint that granting this thread the read lock is more important than granting another thread a write lock.
void rdlock(bool high_priority = false);
// Release the obtained read lock.
void rdunlock();
// Block until it's safe to write to the data.
void wrlock();
// Release the obtained write lock.
void wrunlock();
// Convert the obtained write lock into a read lock.
void wr2rdlock();
// Block until it is possible to convert the obtained read lock into a write lock.
void rd2wrlock();
// Return true when a read or write is obtained and subsequent calls to release the lock are expected.
bool isLocked() const;
};
* Call a virtual terminated() that by default sets mStatus to STOPPED,
instead of setting it to STOPPED directly, allowing to override
the behavior of a LLThread derived class when the thread is about
the exit.
* Make setQuitting() public, so it can also be used to hint to a
thread that it should stop at its earliest convience.

One diff added /MP to CMAKE_CXX_FLAGS_DEBUG while
another removed /arch:SSE2 from the same line.
Fixed to honor both changes.
Conflicts:

Added /* */ around the 'virtual' keyword in two places
that collided with changes in meshupload from lightdrake.
