* lisp/org-element.el (org-element-drawer-re-nogroup): New constant
regexp matching drawer line without creating regexp groups.
(org-element--current-element): Use the new constant.
* lisp/org.el (org-drawer-regexp): Ensure that it is the same with
org-element version and mark for removal/alias.
(org-property-drawer-re): Simplify, removing unnecessary matching of
node property structures.

(org-element--cache-sync):
(org-element--cache-process-request):
(org-element--parse-to):
(org-element--cache-submit-request):
(org-element--cache-for-removal): use `org-element-property-1' to
retrieve parent without checking if it is deferred. All the cached
elements have proper parent.
* lisp/org-element.el (org-element--cache-variables): New constant
holding variables involved in cache state.
(org-element-cache-reset): Fix modification hooks when cache is reset
and buffer already have indirect child buffers.
(org-element-with-enabled-cache): New macro, to enable cache around
body.
(org-element-cache-map): Enable cache when executing.
* lisp/org-element.el: Add commentary explaining some regexp-related
optimizations useful for the parser.

necessary. Explain the necessity in places where we have to use
`save-match-data'. Prefer `looking-at-p' (does not alter match data)
to `looking-at'. Simplify regexps. Update docstrings clearly
indicating when match data might be modified.

Update all the relevant code in Org to use the new functions instead
of genetic property queries.
