2017-10-02[cmake] Add a separate CMake var to control profile runtimeMichal Gorny
Make it possible to control building profile runtime separately from other options. Before r313549, the profile runtime building was controlled along with sanitizers. However, since that commit it is built unconditionally which results in multiple builds for people building different runtimes separately.

2017-09-27[Sanitizers] Allocator: new "release memory to OS" implementationAlex Shlyapnikov
Summary: The current implementation of the allocator returning freed memory back to OS (controlled by allocator_release_to_os_interval_ms flag) requires sorting of the free chunks list, which has two major issues, first, when free list grows to millions of chunks, sorting, even the fastest one, is just too slow, and second, sorting chunks in place is unacceptable for Scudo allocator as it makes allocations more predictable and less secure. The proposed approach is linear in complexity (altough requires quite a bit more temporary memory). The idea is to count the number of free chunks on each memory page and release pages containing free chunks only. It requires one iteration over the free list of chunks and one iteration over the array of page counters. The obvious disadvantage is the allocation of the array of the counters, but even in the worst case we support (4T allocator space, 64 buckets, 16 bytes bucket size, full free list, which leads to 2 bytes per page counter and ~17M page counters), requires just about 34Mb of the intermediate buffer (comparing to ~64Gb of actually allocated chunks) and usually it stays under 100K and released after each use. It is expected to be a relatively rare event, releasing memory back to OS, keeping the buffer between those runs and added complexity of the bookkeeping seems unnesessary here (it can always be improved later, though, never say never). The most interesting problem here is how to calculate the number of chunks falling into each memory page in the bucket. Skipping all the details, there are three cases when the number of chunks per page is constant: 1) P >= C, P % C == 0 --> N = P / C 2) C > P , C % P == 0 --> N = 1 3) C <= P, P % C != 0 && C % (P % C) == 0 --> N = P / C + 1 where P is page size, C is chunk size and N is the number of chunks per page and the rest of the cases, where the number of chunks per page is calculated on the go, during the page counter array iteration. Among the rest, there are still cases where N can be deduced from the page index, but they require not that much less calculations per page than the current "brute force" way and 2/3 of the buckets fall into the first three categories anyway, so, for the sake of simplicity, it was decided to stick to those two variations. It can always be refined and improved later, should we see that brute force way slows us down unacceptably.

Summary: Previous parts: D38139, D38183. In this part of the refactor, we abstract the Linux vs Android TSD dissociation in favor of a Exclusive vs Shared one, allowing for easier platform introduction and configuration. Most of this change consist of shuffling the files around to reflect the new organization. We introduce `scudo_platform.h` where platform specific definition lie. This involves the TSD model and the platform specific allocator parameters. In an upcoming CL, those will be configurable via defines, but we currently stick with conservative defaults.

2017-09-25[scudo] Scudo thread specific data refactor, part 2Kostya Kortchinsky
Summary: Following D38139, we now consolidate the TSD definition, merging the shared TSD definition with the exclusive TSD definition. We introduce a boolean set at initializaton denoting the need for the TSD to be unlocked or not. This adds some unused members to the exclusive TSD, but increases consistency and reduces the definitions fragmentation. We remove the fallback mechanism from `scudo_allocator.cpp` and add a fallback TSD in the non-shared version. Since the shared version doesn't require one, this makes overall more sense. There are a couple of additional cosmetic changes: removing the header guards from the remaining `.inc` files, added error string to a `CHECK`. Question to reviewers: I thought about friending `getTSDAndLock` in `ScudoTSD` so that the `FallbackTSD` could `Mutex.Lock()` directly instead of `lock()` which involved zeroing out the `Precedence`, which is unused otherwise. Is it worth doing?

Summary: We are going through an overhaul of Scudo's TSD, to allow for new platforms to be integrated more easily, and make the code more sound. This first part is mostly renaming, preferring some shorter names, correcting some comments. I removed `getPrng` and `getAllocatorCache` to directly access the members, there was not really any benefit to them (and it was suggested by Dmitry in D37590). The only functional change is in `scudo_tls_android.cpp`: we enforce bounds to the `NumberOfTSDs` and most of the logic in `getTSDAndLockSlow` is skipped if we only have 1 TSD.
