Jocelyn Turcotte 2b274e9460 Fix the MSVC build
- Replace functions that are provided by MinGW with a Win32-based
  implementation
- Explicitly export needed symbols from ocsync.dll
- Rename share.h to sharemanager.h since the name clashes with one
  of the Windows headers and get included from there
- Remove the timestamp from the fallback csync stderr logging, it's
  not used since we always provide a log callback
