Pull request description:
Rationale:
* `delete ptr` is a no-op if `ptr` is `nullptr`

This patch removes the need for the intermediary Base58 type
CBitcoinAddress, by providing {Encode,Decode,IsValid}Destination
function that directly operate on the conversion between strings
and CTxDestination.

- add static verifySize() function to PaymentServer and move the logging
on error into the function
- also use the new function in the unit test
- the function checks if the size is allowed as per BIP70
QT_NO_KEYWORDS prevents Qt from defining the `foreach`, `signals`,
`slots` and `emit` macros.
Avoid overlap between Qt macros and boost - for example #undef hackiness
in #6421.
Before and after was tested in Windows:
before:
GUI: ReportInvalidCertificate : Payment server found
an invalid certificate: ("Microsoft Authenticode(tm) Root Authority")
GUI: ReportInvalidCertificate : Payment server found
an invalid certificate: ()
GUI: ReportInvalidCertificate : Payment server found
an invalid certificate: ()
GUI: ReportInvalidCertificate : Payment server found
an invalid certificate: ()
after:
GUI: ReportInvalidCertificate: Payment server found an
invalid certificate: "01" ("Microsoft Authenticode(tm) Root Authority")
() ()
GUI: ReportInvalidCertificate: Payment server found an
invalid certificate: "01" () () ("Copyright (c) 1997 Microsoft Corp.",
"Microsoft Time Stamping Service Root", "Microsoft Corporation")
GUI: ReportInvalidCertificate: Payment server found an
invalid certificate: "4a:19:d2:38:8c:82:59:1c:a5:5d:73:5f:15:5d:dc:a3" ()
() ("NO LIABILITY ACCEPTED, (c)97 VeriSign, Inc.", "VeriSign Time Stamping
Service Root", "VeriSign, Inc.")
GUI: ReportInvalidCertificate: Payment server found an
invalid certificate: "e4:9e:fd:f3:3a:e8:0e:cf:a5:11:3e:19:a4:24:02:32" ()

This makes it easier for us to replace it if desired, since it's now only in
one spot. Also, it avoids the openssl include from allocators.h, which
essentially forced openssl to be included from every compilation unit.
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
- now logs if -rootcertificates="" was used to disable payment request
authentication via X.509 certificates
- also logs which file is used as trusted root cert, if -rootcertificates
is set
- this is based on #4122 (which can be closed)
Currently a payment request is only checked for expiration upon receipt.
It should be checked again immediately before sending coins to prevent
the user from paying to an expired invoice which would then require a
customer service interaction.
- add static verifyExpired() function to PaymentServer to be able to use
the same validation code in GUI and unit-testing code
- extend unit tests to use that function and also add an unit test which
overflows, because payment requests allow expires as uint64, whereas we
use int64_t for verification of expired payment requests
- verify that payment request network matches client network
- add static verifyNetwork() function to PaymentServer to be able to use
the same validation code in GUI and unit-testing code
- current code only does this for payment request files, which are
used on Mac
- also rename readPaymentRequest to readPaymentRequestFromFile, so it's
obvious that function only handles payment request files and not URIs
- small logging changes in readPaymentRequestFromFile
