* ox-latex.el (org-latex-listings-langs): Change the binding for
  `ocaml' to "[Objective]Caml"

The "[Objective]Caml" dialect syntax highlighting is different from the
"Caml" one (reflecting the added features of OCaml compared to
Caml-light).

TINYCHANGE

* mk/org-fixup.el (org-make-org-version): Add lexical-binding cookie
to autogenerated files.
* lisp/org-install.el: Use lexical-binding.

* ox-latex.el (org-latex-export-to-pdf):  The documentation for
`org-latex-pdf-process' states that "%bib" will be expanded into the
current binding of `org-latex-bibtex-compiler'.  However, the
`org-latex-export-to-pdf', where the expansion takes place, expects
"%bibtex" instead.  This fix will accept "%bib" as well as "%bibtex"
as markers for `org-latex-bib-compiler'.

This fixes a regression from f6187dec (ox-latex: Small refactor,
2015-09-13).

TINYCHANGE

* testing/lisp/test-org-macs.el (test-org-matcher-time): Add tests.

This includes of a test for the missing hour modifier added in the
previous commit.

* lisp/org-macs.el (org-matcher-time): Handle hour ("h") time stamp
modifier.
* doc/org-manual.org (The date/time prompt): Document hour modifier.

This adds support for date expressions such as +12h to
org-matcher-time. The regexp this function uses to parse such relative
expressions already includes the "h" character but doesn't actually
handle that case.

AFAICT org-mode commit ec921a2a ("Support hourly repeat cookies")
neglected to add support here.

TINYCHANGE

* contrib/lisp/org-contacts.el (org-contacts-link-open): Display the
searched contacts file buffer.

* lisp/ox-md.el (org-md-link): Format markdown hyperlink from radio
target.

TINYCHANGE

* lisp/ox-html.el (org-html-meta-tags): Introduce this as a new option
which can be modified to set the meta tags added in HTML exports.
(org-html--build-meta-info): Make use of `org-html-meta-tags' instead of
hardcoded meta tags.  This is leveraging the earlier restructuring of
`org-html--build-meta-info' into a much DRYer form, such that this
modification has a negligible impact on complexity and readability.

* lisp/ox-html.el (org-html--build-meta-info): Multi-line repeated
structure extracted to new function `org-html--build-meta-entry'.
The keyword value formatting is changed from `org-export-data' to
`org-html-encode-plain-text' to avoid potentially nesting HTML tags in
meta tags and the <title> element, which would violate W3C.

lisp/ob-java.el: Allow source block headers to override the java
compiler or runtime commands.

Currently the java compiler and runtime commands are customizable, but
cannot be overridden locally in source block hearders.  ob-python
allows overriding the runtime command and I've found it to be useful.
This does the same for ob-java.

* lisp/ob-java.el (org-babel-java--imports-re): Include static imports
in Java import regex.

TINYCHANGE

* lisp/ob-C.el (org-babel-C-utility-header-to-C): Add declaration of
  strcmp() for C and C++.

* testing/examples/ob-C-test.org (Simple tests): Remove a spurious \n
  new line.

* org-footnote.el (org-footnote-create-definition): Replace
  `forward-line' with `org-end-of-meta-data' to skip over any
  properties and/or drawers that may be present on the
  `org-footnote-section' heading (default "Footnotes").

TINYCHANGE

* lisp/org.el (org-fast-tag-selection): Merge buffer local tags with
global alist of tags. And it obeys the option
org-complete-tags-always-offer-all-agenda-tags.

* doc/org-manual.org: Update the TAB key doc in tags selection UI.

* etc/ORG-NEWS: Mention the change in org-set-tags-command.

* testing/lisp/test-org-archive.el
(test-org-archive/datetree): Fix test for locales that don't use
English weekday names.

* lisp/org-compat.el (org-copy): Move from org-refile.el.
* lisp/org-refile.el (org-copy): Move to org-compat.el.

* contrib/lisp/org-contacts.el (org-contacts-link-store): Fix
org-store-link return incorrect link without link type prefix.

* org-contacts.el (org-contacts-link-store): Use `bound-and-true-p' to
check the truthiness of org-id-link-to-org-use-id, which may or may
not be bound depending on whether org-id has been loaded.  This
simplifies the code.

* lisp/ol.el (org-store-link): Use completing-read's DEF argument
rather than INITIAL-INPUT, which is discouraged (see Elisp manual) and
may hide the other choices depending on the completion framework.

Fixes bug introduced in 6b83c6e4 that made org-contacts-anniversaries
error if org-id was not loaded.

* lisp/org-duration.el (org-duration-units): Guard against recursive
load error when org-duration-units is set via the Customize interface
before org-duration is loaded.

This follows the same approach used by erc-nickserv-identify-mode in
the Emacs repository.

* contrib/lisp/org-contacts.el (org-contacts-get-icon): replace obsolete
alias `loop' with `cl-loop'.

* contrib/lisp/org-contacts.el: Add usage comments.

* lisp/org-plot.el (org--plot/values-stats): Replace `log10' with
`log'.
(org--plot/nice-frequency-pick): Replace obsolete `case' with `cl-case`.
(org--plot/radar): Replace `s-join' with `mapconcat', removing the
implicit dependency on s.el.
(org-plot/gnuplot-script): Remove unused let bindings.
(org-plot/gnuplot-script): Replace free variable reference with
expression only using given variables.

de6d9022 (org-attach: Consider inlinetasks when calculating attach
dir, 2020-12-17) introduced a call to org-inlinetask-goto-beginning
and org-inlinetask-in-task-p, each behind a featurep guard.

* lisp/org-plot.el (org-plot/gnuplot): Make recently introduced pcase
call compatible with Emacs 24.

Despite .dir-locals.el having a catchall value of t for
indent-tabs-mode, Org's Elisp files are a mix of tabs and spaces.
Emacs has used a value of nil for indent-tabs-mode since 93d4412046
(Set indent-tabs-mode to nil in (most) Elisp sources, 2015-04-15).  Do
the same.
