Summary:
Please consider this small PR providing access to the `MemoryUsage::GetApproximateMemoryUsageByType` function in plain C API. Actually I'm working on Go application and now trying to investigate the reasons of high memory consumption (#4313). Go [wrappers](https://github.com/tecbot/gorocksdb) are built on the top of Rocksdb C API. According to the #706, `MemoryUsage::GetApproximateMemoryUsageByType` is considered as the best option to get database internal memory usage stats, but it wasn't supported in C API yet.

Summary:
As you know, almost all compilers support "pragma once" keyword instead of using include guards. To be keep consistency between header files, all header files are edited.
Besides this, try to fix some warnings about loss of data.

Summary:
Top-level index in partitioned index/filter blocks are small and could be pinned in memory. So far we use that by cache_index_and_filter_blocks to false. This however make it difficult to keep account of the total memory usage. This patch introduces pin_top_level_index_and_filter which in combination with cache_index_and_filter_blocks=true keeps the top-level index in cache and yet pinned them to avoid cache misses and also cache lookup overhead.

SUMMARY
Moves the bytes_per_sync and wal_bytes_per_sync options from immutableoptions to mutable options. Also if wal_bytes_per_sync is changed, the wal file and memtables are flushed.
TEST PLAN
ran make check
all passed
Two new tests SetBytesPerSync, SetWalBytesPerSync check that after issuing setoptions with a new value for the var, the db options have the new value.

Summary:
I've added functions to the C API to support WriteBatchWithIndex as requested in #1833.
I've also added unit tests to c_test
I've implemented the WriteBatchWithIndex variation of every function available for regular WriteBatch. And added additional functions unique to WriteBatchWithIndex.
For now, the following is omitted:
1. The ability to create WriteBatchWithIndex's custom batch-only iterator as I'm not sure what its purpose is. It should be possible to add later if anyone wants it.
2. The ability to create the batch with a fallback comparator, since it appears to be unnecessary. I believe the column family comparator will be used for this, meaning those using a custom comparator can just use the column family variations.
