can't be disabled by setting it to "no" like the other variables.

Make PKG_DEVELOPER DWIM.

Added a new check for all C and C++ header files to make sure they don't
contain strings like ${prefix} or ${exec_prefix}, which is currently a
problem with sysutils/dbus and has been noticed in PR 35019. This check
is disabled by default since I don't know anything about possible false
positives, but I plan to enable it for PKG_DEVELOPERs after some
testing.
Added two names for hooks that are placed in the configure and in the
build phase. Now the checks look more like becoming something one could
call a framework, sharing a common structure and a documented interface.
