[Qt] prevent amount overflow problem with payment requests
Bitcoin amounts are stored as uint64 in the protobuf messages (see
paymentrequest.proto), but CAmount is defined as int64_t. Because
of that we need to verify that single and accumulated amounts are
in a valid range and no variable overflow has happened.
- fixes #5624 (#5622)
Thanks @SergioDemianLerner for reporting that issue and also supplying us
with a possible solution.
- add static verifyAmount() function to PaymentServer and move the logging
on error into the function
- also add a unit test to paymentservertests.cpp
