Bug 1342102 - Use the same threading structure in platform-linux-android.cpp as for the -macos and -win32 versions. r=n.nethercote. The MacOS and Windows profiler cores have a threading structure where one thread ("sampler thread") collects information from a thread to be profiled ("samplee thread") by suspending it, getting its register state, unwinding its stack, and then resuming it. This requires kernel-level primitives to perform the suspend, get-registers and resume steps. The Linux/Android core is different, because none of those three primitives exist. Until now, data collection has been done by sending a SIGPROF to the samplee, and collecting all relevant data within the signal handler. This has a number of disadvantages: (1) Current work to rationalise/clean up the threading structure of the profiler is complicated by the need to reason about/verify two different schemes. In particular, the Tick call in the Windows and MacOS implementations will produce its output on the sampler thread. In the Linux implementation that is produced on the sampled threads. (2) Dynamic verification results (primarily, absence of data races and deadlocks) established for the Linux implementation are less likely to carry over to the other two implementations, because the threading structures are different. (3) It causes a lot of duplicated code in platform-*.cpp. For example SamplerThread::Run() in the -win32.cpp and -macos.cpp files are very similar. Ideally all three could be merged into a single file with the identical logic commoned up. (4) Running lots of code -- the entire contents of Tick -- in a signal handler isn't considered good practice. POSIX severely restricts the set of functions we can safely call from within a signal handler. This commit changes the Linux implementation by using semaphores to implement the suspend and resume primitives, and moves the bulk of the data collection work to the sampler thread. By doing this, it causes the Linux implementation to have the same threading structure as the other two.
