* lisp/org-element.el (org-element-dynamic-block-open-re-nogroup):
(org-element--latex-begin-environment-nogroup): New constants for
internal regexps.
(org-element-comment-parser):
(org-element--current-element-re):
(org-element--current-element): Prefer string constants instead of
repeated plain strings that may be considered different by Emacs
regexp compiler. Also, avoid groups in these regexps as creating
groups makes Emacs regexp matches allocate extra memory. Finally,
avoid using \{N\} constructs in regexps as they are slightly more
costly for regexp engine.
* lisp/org-element.el (org-element--current-element): Slight
optimization of checking for property drawer at point. `forward-line'
is significantly faster compared to `beginning-of-line'.
`skip-chars-forward' also provides a bit of improvement compared to
`looking-at-p'.

* lisp/org-element.el (org-element-node-property-parser): Remove
unnecessary `re-search-forward'. It always triggers as long as
`org-property-drawer-re' only allow node properties inside property
drawer. Also, remove unnecessary `case-fold-search' setting that has
no meaning since we do not match against specific letters.
* lisp/org-list.el (org-item-re): Use faster `defsubst'. This
function is called very frequently when parsing Org buffers by
`org-element--current-element'.
* 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.

`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.

Adjust all the declare forms.

* lisp/org-element.el (org-element-map): Treat TYPES t as all possible
types. Add new optional parameter to no resolve deferred while
traversing the AST.
