try to move partial scan logic into general compile stage , then we can support partial when delimiter changed (now buggy)
fix partial bug
reduce unused , or . to make speed faster
refine doc, add FLAG_MUSTACHE ( = FLAG_MUSTACHESP + FLAG_MUSTACHELOOKUP now )
add FLAG_RUNTIMEPARTIAL (behavior not implementd yet)
compile partials for FLAG_RUNTIMEPARTIAL , later do real implement
no need return, and remove related tests
remove one testcase (unnecessary?)
support runtime partial
refine tests for partial
test on recursive
skip 4 issues now lighncandy still not handled
