Introduces a configure flag --enable-experimental that controls at
configure time whether or not experimental features can be
enabled. This serves as a circuit breaker to both make sure that
CI jobs are configured properly, and ensures manual compilations
are intentionally configuring experimental / non-production code.
Additionally, experimental features get listed in the summary after
configuration completes if enabled.
Further work can insert compile time checks with static_asserts
against the ALLOW_DOGECOIN_EXPERIMENTAL macro.

Newer compilers may switch to newer standards by default. For example, gcc6
uses std=gnu++14 by default.

Add environment settings to specify the CFLAGS and LIBS to be used for
BerkeleyDB directly. These will completely by-pass autodetection in the
same way as other similar flags.

Implements #3921.
The non-pkg-config case can't use pkg-config to check the version.
Also, make sure that the check is properly guarded in the case of missing
pkg-config macros.
Qt5 is bottled, so configure won't find it without some help. Use
brew to find out its prefix.
Also, qt5 added the host_bins variable to pkg-config, use it.
