there are two x extensions for working with monitors (especially
multiple): xinerama and randr. xinerama is old, feature-poor and in
general isn't used anymore compared to the randr: new, feature-rich and
widely-used. for some reason we were using both of them, so let's drop
xinerama to keep things simple, clean and small. and to be modern.
the drop was done in three steps:
* first step was to replace all the xinerama-based code with the
randr-based one and to replace or remove all the xinerama mentions;
* second step was to replace the xinerama's terminology with the
randr's one. xinerama was referring only to the word "screen", while
randr refers to multiple words and i think the word "monitor" is the
most suitable for us and, hopefully, clear both to a contributor and
to an end user;
* third step was to refactor the new randr-based code if needed and to
address related todo's (mostly about moving related functions
elsewhere).
all the steps were done well except addressing a leftover todo about
moving the win_update_monitor function to the x.c which wasn't done.
the xinerama-shadow-crop option was renamed to crop-shadow-to-monitor,
but it's previous name is still accepted, has effect and the
deprecation message is printed to preserve backwards-compatibility.
Use the DPMS extension to detect if screen is turned off, and unredirect
if it is. This also helps working around the problem where OpenGL
buffers lose data when screen is turned off, causing screen to flicker
later when it turns back on if use-damage is enabled.
Unfortunately the DPMS extension doesn't define an event, so we have to
periodically poll the screen state.

this fixes `WARNING: Running the setup command as `meson [options]` instead of `meson setup [options]` is ambiguous and deprecated.` warning while setting up the project
The picom project is no longer a fledgling fork needing to justify its
existence. The README should present the user with relevant information
regarding the current project rather than apologies for a 6-year-old
fork of a longer-defunct prior project.
1. Rename README_orig.md to History.md, so it can contain other content
of a historical nature.
2. Move still-relevant historical content from README to History.
3. Add a brief intro blurb to README saying that picom is an X
compositor.
4. Mention Compton in the CONTRIBUTORS section.
5. Point to licensing information from README.
Rationale:
- "bug to be expected" -> "bugs to be expected". Usually the noun is plural in this expression (since more than one bug is likely to be found in the future).
- "because that seems to be unmaintained" -> "because it seems to be unmaintained". Using a demonstrative pronoun ("that") versus a personal pronoun ("it") suggests that we need to specify which of several Comptons is unmaintained.
- "features" -> "feature" and "stabilizes" -> "stabilize". The new backends are plural, should be conjugated without the trailing "s".
- "used" -> "use". The command used to launch picom has already been run. Changing to "use" indicates the command that habitually launches picom. Also changed "command line" (the interface, e.g. the prompt) to "command".
- "Rational" (adjective: based on reason) -> "Rationale" (noun: the reasons or logic that motivated an action)
- "when people searches" -> "when people search". Usually conjugated as plural [1](https://english.stackexchange.com/q/263046)
- "to solve aforementioned problems" -> "to solve the aforementioned problems". "Aforementioned" is preceded by a definite article when modifying a noun.
- "mentions to" (usually used in suggesting an 'honourable mention'/accolade regarding somebody) -> "mentions of" (instances of)
It could be hard for Ubuntu/Debian users to find the correct packages
for the dependencies.

Also add a new config file path:
{$XDG_CONFIG_DIRS,$XDG_CONFIG_HOME}/compton/compton.conf
(For those not familiar with xdg: now compton will look for
~/.config/compton/compton.conf too)
Closes#62

It will cause compton to print out some rudimentary diagnostics.
Also small improvements of the meson.build.

IANAL, but I think I am allowed to add missing copyright notices for
someone else. And I did my best job using git history to figure out who
wrote which functions. So I hope everything is fine.
- Fix OpenGL 3.0 compatibility by changing glFramebufferTexture() to
glFramebufferTexture2D(). Thanks to danfe for suggestion!
- Add notification about DocBook toolchina dependencies. Thanks to
danfe. (#121)
- Add --opacity-rule, which sets opacity based on conditions, as
requested by zabbal. (#113)
- Add a data field for each condition.
- Correct the FAQ link in README.md. Silly me.
- Code clean-up.
