Vitaliy Filippov 38db53f5ee Implement client writeback cache 
- Disabled by default, enable with client_enable_writeback=true

- Can also be enabled in other clients like vitastor-cli using parameter
  client_writeback_allowed=true, but not recommended

Vitaliy Filippov 7bdd92ca4f Fix build under clang and some warnings 
Build problems fixed:
- void* pointer arithmetic which is a GNU extension (works as byte*)
- "variable size object may not be initialized" which is OK under GCC
- nullptr_t related error in json11 (it lacks 'operator <' in clang)

Warnings fixed:
- empty nested struct initializer { 0 } replaced by {}
- removed several unused lambda captures

Vitaliy Filippov 891250d355 Implement CAS writes 
From now on, reads will return the server-side object version numbers
and writes and deletes will have an additional "version" parameter
which, if set to a non-zero value, will be atomically compared with
the current version of the object plus 1 and the modification will
fail if it doesn't match.

This feature opens the road to correct online flattening of snapshot
layers and other interesting things.
