pageflags: introduce macros to generate page flag functions
Introduce a set of macros that generate functions to handle page flags.
A page flag function group typically starts with either
SETPAGEFLAG(<part of function name>,<part of PG_ flagname>)
to create a set of page flag operations that are atomic. Or
__SETPAGEFLAG(<part of function name>,<part of PG_ flagname)
to create a set of page flag operations that are not atomic.
Then additional operations can be added using the following macros
TESTSCFLAG Create additional atomic test-and-set and
test-and-clear functions
TESTSETFLAG Create additional test and set function
TESTCLEARFLAG Create additional test and clear function
SETPAGEFLAG Create additional atomic set function
CLEARPAGEFLAG Create additional atomic clear function
__TESTPAGEFLAG Create additional non atomic set function
__SETPAGEFLAG Create additional non atomic clear function
