Update fbcode_config.sh so that It try to use the latest version for dependencies that we are using, after updating the code these libraries where updated
```
Snappy: 1.0.3 => 1.1.3

I have also updated clang from 3.7 to 3.7.1

Another change is that we use the same tp2 directory as fbcode, so we dont need to keep changing commit hash every time we need to change a version of a compiler or a library

Summary:
Remove the SyncPoint usage in the destructor of PosixEnv as none
of any active tests is using it.
SyncPoint is a test-only utility class, and it's a static varible.
As a result, using SyncPoint in the destructor of PosixEnv will
make default Env depends on SyncPoint. Removing such dependency
could solve the problem crash issue only reproducable in Mac
environment.

Summary:
When a child thread that uses ThreadLocalPtr, ThreadLocalPtr::OnThreadExit
will be called when that child thread is destroyed. However,
OnThreadExit will try to access a static singleton of ThreadLocalPtr,
which will be destroyed when the main thread exit. As a result,
when a child thread that uses ThreadLocalPtr exits AFTER the main thread
exits, illegal memory access will occur.
This diff includes a test that reproduce this legacy bug.

This patch fix this issue by having the thread local mutex never be deleted

Summary:
InlineSkipList::InsertConcurrently should invalidate the
sequential-insertion cache prev_[] for all inserts of multi-level nodes,
not just those that increase the height of the skip list. The invariant
for prev_ is that prev_[i] (i > 0) is supposed to be the predecessor of
prev_[0] at level i. Before this diff InsertConcurrently could violate
this constraint when inserting a multi-level node after prev_[i] but
before prev_[0].

Test Plan:
1. unit tests

Summary: When L0->L1 is pending, there may be one L1->L2 compaction going on which prevents the L0->L1 compaction from happening. If L1 needs more data to be moved to L2, then we may continue scheduling more L1->L2 compactions. The end result may be that L0->L1 compaction will not happen until L1 size drops to below target size. We can reduce the stalling because of number of L0 files by stopping schedling new L1->L2 compaction when L0's score is higher than L1.

Summary:
This set of changes implements the following design: `ldb` will utilize `--path` parameter which can be used to specify a file name. Tool will then apply some heuristic to determine how to output the data properly. The design decision is not to probe the file content, but use file names to determine what dumping function to call.
Usage examples:
Understands that path points to a manifest file and dumps it.
`./ldb --path=/tmp/test_db/MANIFEST-000023 dump`
Understands that path points to a WAL file and dumps it.
`./ldb --path=/tmp/test_db/000024.log dump --header`
Understands that path points to a SST file and dumps it.
`./ldb --path=/tmp/test_db/000007.sst dump`
Figures out that none of the supported file types are applicable and outputs
an appropriate error message.
`./ldb --path=/tmp/cron.log dump`

PrefixMayMatch previously seeked in the prefix index using an internal
key with a sequence number of 0. This would cause the prefix index seek
to fall off the end if the last key in the index had a user-key greater
than or equal to the key being looked for. Falling off the end of the
index in turn results in PrefixMayMatch returning false if the index is
in memory.
Summary:
See a bug report here: https://github.com/facebook/rocksdb/issues/921
