Since we're now properly linking against static plugins for qt binaries,
we need to ensure that they're Imported properly.
Without these Imports, the linker drops some of the unused linked libs, causing
undefined symbols in QtCore.
- make eventFilter() private and pass events on to QObject::eventFilter()
instead of just returning false
- re-work paymentservertest.cpp to correctly handle the event test
after the above change (rewrite test_main to allow usage of
QCoreApplication:: in the tests)
- delete socket when we were unable to connect in ipcSendCommandLine()
- show a message to the user if we fail to start-up (instead of just a
debug.log entry)
- misc small comment changes
Use misc methods of avoiding unnecesary header includes.
Replace int typedefs with int##_t from stdint.h.
Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h.
Normalize QT_VERSION ifs where possible.
Resolve some indirect dependencies as direct ones.
Remove extern declarations from .cpp files.
Add support for a Payment Protocol to Bitcoin-Qt.
Payment messages are protocol-buffer encoded and communicated over
http(s), so this adds a dependency on the Google protocol buffer
library, and requires Qt with OpenSSL support.
