project-wide: build & run-time fixes

While using meson some issues were faced with link and application
startup. This commit is to put fixes for the following issues:

- missed conversation_details.css file;
  add conversation_details.css to the main/data/gresources.xml;
- the 'localtime_r' symbol  can't be found while linking application
  add POSIX_C_SOURCES=1 macro definition
- meson configure complains that xmpp-vala package version is not set
  set xmpp-vala version to 0.1
- application startup failures due to unresolved symbols while creating
  initial UI
   fix: put '--export-all-symbols' to the main/meson.build for mingw64 build
- segmentation fault while running app built by meson
  meson.build: add _WIN32 definefor vala compilation
- main/meson.build: add _FILE_OFFSET_BITS definition (sync with cmake
  cfg)
- main/meson.build: compile window resources (fix missed window icon)
