See the attached patch set adding support of compat.el.

I had to update Org's build system to handle third-party packages.
Please, give it a close check (first patch).

The second patch adds the actual Elisp part and replaces some
compatibility functions with what is provided by compat.el.
Note that not all the functions are available in compat.el for now.
Daniel, you might want to take a look.

The last patch adds the necessary explanation for users who install Org
from git. Now, they must install compat.el manually to make Org work.

Subject: [PATCH 1/3] Upgrade Org build system to handle third-party
 dependencies

* mk/default.mk (pkgdir): New variable holding the location of
third-party packages to be downloaded if necessary during compilation.
(EFLAGS): New variable holding extra flags to be passed to Emacs
executable when running make.
(EPACKAGES): List of packages to be installed (unless already present
in the `load-path') during compilation.
(package-install):
(INSTALL_PACKAGES): New command to download and install missing packages.
(BATCH): Update, setting default package location to pkgdir.
* mk/targets.mk (uppkg): New target to download install missing
packages.
(check test):
(compile compile-dirty): Use the new uppkg target.
(cleanpkg): New target cleaning up the downloaded packages.
(cleanall): Use the new target.
(.PHONY):
(CONF_BASE):
(CONF_DEST):
(CONF_CALL): Update according to the new variables and targets.
* .gitignore: Ignore the downloaded packages.

This commit paves the way towards third-party built-time dependencies
for Org.  In particular, towards including compat.el dependency.

According to EPACKAGES, we can auto-download necessary packages,
unless they are manually specified via -L switches in EFLAGS.
