Soli f1837595a3 FIX #3278: Move global const object definitions from .h to .cc (#4691) 
Summary:
Summary

We should declare constants in headers and define them in source files.
But this commit is only aimed at compound types.

I don't know if it is necessary to do the same thing to fundamental types.

I used this command to find all of the constant definitions in header files.

`find . -name "*.h" | xargs grep -e "^const .*=.*"`

And here is what I found:

```
./db/version_edit.h:const uint64_t kFileNumberMask = 0x3FFFFFFFFFFFFFFF;
./include/rocksdb/env.h:const size_t kDefaultPageSize = 4 * 1024;

./utilities/cassandra/serialize.h:const int32_t kBitsPerByte = 8;
```

And these 3 lines are related to this commit:

```
./include/rocksdb/statistics.h:const std::vector<std::pair<Tickers, std::string>> TickersNameMap = {
./include/rocksdb/statistics.h:const std::vector<std::pair<Histograms, std::string>> HistogramsNameMap = {
./util/trace_replay.h:const std::string kTraceMagic = "feedcafedeadbeef";
```

Any comments would be appreciated.
Thanks.
