Message:

Add WTF infrastructure for the BlackBerry port
​https://bugs.webkit.org/show_bug.cgi?id=72970

Reviewed by Antonio Gomes.

• wtf/Assertions.cpp: Added BlackBerry-specific logging directive.
• wtf/MathExtras.h:

(abs): Added; stdlib doesn't contain abs() on QNX.

• wtf/Platform.h: Define WTF_PLATFORM_BLACKBERRY and enable some platform features.
• wtf/RandomNumberSeed.h:

(WTF::initializeRandomNumberGenerator): For the BlackBerry port, we initialize
the bad pseudo random number generator using time(3) before initializing the
Mersenne Twister random number generator.

• wtf/ThreadingPthreads.cpp:

(WTF::createThreadInternal): Added.

• wtf/blackberry: Added.
• wtf/blackberry/MainThreadBlackBerry.cpp: Added.

(WTF::initializeMainThreadPlatform):
(WTF::scheduleDispatchFunctionsOnMainThread):

• wtf/text/WTFString.h: Added constructor and conversion operator for

BlackBerry WebString string object.
