Log Message:
-----------
Define a third kind of COW state; STATIC
Previously, when IsCOW flag was set there were two cases:
SvLEN()==0:
PV is really a shared HEK
SvLEN()!=0:
PV is a COW structure with 1..256 refcount stored in its extra final byte
This change adds a third state:
SvLEN()==0 && SvFLAGS() & SVppv_STATIC:
PV is a shared static const pointer and must not be modified
sv_setsv_flags() and sv_setsv_cow() will preserve this state
sv_uncow() will copy it out to a regular string buffer
sv_dup() will preserve the static pointer into cloned threads

Log Message:
-----------
Add SvIsBOOL() macro to test for SVs being boolean-intent
These are identified as being static shared COW strings whose string
buffer points directly at PL_Yes / PL_No
Define sv_setbool() and sv_setbool_mg() macros
Use sv_setbool() where appropriate
Have sv_dump() annotate when an SV's PV buffer is one of the PL_(Yes|No)
special booleans

Add a Scalar::Util::isbool()
Remember to SvGETMAGIC() before testing SvIsBOOL() (thanks @tonycoz)
Unit-test that booleaness is preserved on values passed in to, out of, or
captured by threads
