Add a --version flag that prints PACKAGE_VERSION.

Thanks! |

Yeah, it's kind of a silly reason but it's the last thing I need to have this fully packageable with a man page and everything for both fedora and RHEL via EPEL. Otherwise the version shows up as "unknown" on RHEL. :/ |

Summary: A failing (on OSX) test case as evidence that the current OSX implementation doesn't notice file changes.
Test Plan:
unit test
Here is the full unit test suite output (`make integration`) - this new test is not the only one failing on OSX. They all also failed before this test, except that this test seems to trigger a failure in the trigger test that isn't there before (some kind of teardown necessary?). Pun intended.

Summary: looking at #96 (comment) we see a trace like: ``` thread #3: tid = 0x16a58c, 0x000000010438cdc0 watchman`w_ht_del frame #0: 0x000000010438cdc0 watchman`w_ht_del frame #1: 0x000000010439aa40 watchman`age_out_dir + 144 frame #2: 0x000000010439aa28 watchman`age_out_dir + 120 frame #3: 0x0000000104398738 watchman`age_out_file + 248 frame #4: 0x000000010439a9ee watchman`age_out_dir + 62 frame #5: 0x0000000104398738 watchman`age_out_file + 248 frame #6: 0x000000010439a9ee watchman`age_out_dir + 62 frame #7: 0x0000000104398738 watchman`age_out_file + 248 frame #8: 0x000000010439a9ee watchman`age_out_dir + 62 frame #9: 0x0000000104398738 watchman`age_out_file + 248 frame #10: 0x000000010439a9ee watchman`age_out_dir + 62 frame #11: 0x0000000104398738 watchman`age_out_file + 248 frame #12: 0x000000010439a9ee watchman`age_out_dir + 62 frame #13: 0x0000000104398738 watchman`age_out_file + 248 frame #14: 0x000000010439a9ee watchman`age_out_dir + 62 frame #15: 0x0000000104398738 watchman`age_out_file + 248 frame #16: 0x000000010439a9ee watchman`age_out_dir + 62 frame #17: 0x0000000104398738 watchman`age_out_file + 248 ``` In cases where we have a large number of files that are eligible to age out across a reasonable number of dirs, we can walk the same portions of the tree we maintain in memory multiple times. This diff records the names of the dir nodes for which we would previously recursively call age_out_dir(); we use a hash to unique the names. After we have walked all eligible file nodes we then iterate the list of saved dirs and delete them. This reduces the complexity of age out processing to a single scan of the file node list followed by a single scan of the list of dirs that we accumulated in the file node scan. Test Plan: `arc unit tests/integration/age.php` exercises this specifically. also: `make integration` a more rigorous test on our www repo: ``` hg up -C master~40000 ; sleep 10 ; hg up -C master ; sleep 10 ; time watchman debug-ageout . 1 hg up -C master~40000 ; sleep 10 ; hg up -C master ; sleep 10 ; time watchman debug-ageout . 1 ``` (it's important to run it twice in succession because we had a long standing bug that we hadn't noticed until now!) The time portion of this outputs: ``` watchman debug-ageout . 1 0.00s user 0.00s system 2% cpu 0.157 total ``` which is a good bit better than 20+ minutes.

Summary: We have seen deadlock running `terminationHandler` -> `hasSubscribers` in 2 threads. It's unclear which other thread is holding the lock. To make things easier to debug next time, let's change terminationHandler (and also main.cpp) to bypass the logging lock and write to stderr directly.
