Summary: Replace exception by setting valid_ = false in DBIter::MergeValuesNewToOld().
Test Plan:
Not sure if I am right at this, but it seems we currently don't have a good
way to test that code path as it requires dynamically set merge_operator = nullptr
at the time while Merge() is calling.

Summary:
Introduces a new class for managing write buffer memory across column
families. We supplement ColumnFamilyOptions::write_buffer_size with
ColumnFamilyOptions::write_buffer, a shared pointer to a WriteBuffer
instance that enforces memory limits before flushing out to disk.
Test Plan: Added SharedWriteBuffer unit test to db_test.cc

Two fixes:
1. if cpplint is not present on the system, don't return a confusing error in the linter
2. Add include_alpha, which means our includes should be sorted lexicographically
Test Plan: Tried unsorting our includes, lint complained

Summary:
In some environment such as android, the c++ library does not have

when std::to_string is not available, and implements std::to_string
in the other case.

Summary:
An entry of ConstantColumnFamilyInfo is created when:
1. DB::Open
2. CreateColumnFamily.
However, there are cases that DB::Open could also call CreateColumnFamily
when create_missing_column_families=true. As a result, it will create
duplicate ConstantColumnFamilyInfo and one of them would be leaked.

Summary:
arena doesn't use huge page by default. This change will make it happen
if possible. A new paramerter is added for Arena(). If it's set, Arena
will use huge page always. If huge page allocation fails, Arena
allocation will fallback to malloc().
Test Plan:
Change util/arena_test to support huge page allocation.
Run below tests:
1. normal regression test:
make check
2. Check if huge page allocation works
echo 50 > /proc/sys/vm/nr_hugepages
make check
