Some cleanup of the coding library:

Browse Source 
1) Removing the obselete api: GetLengthPrefixedSlice(const char*, const char*, Slice*)
as it's not referenced anywhere.
2) A small implementation tweak of GetVarint32/GetVarint64 api:advancing the
input slice past the parsed value using Slice::remove_prefix() instead of
reinitializing *input_slice object.
3) coding_test.cc update.

Test: make check; all tests passed.
