Add units support (POINT, PIXEL, SPACE) (#2578)
* add units support (POINT, PIXEL, SPACE) for polybar

- add a size_with_unit struct
- add a geometry_format_values struct
- move dpi initialisation from renderer.cpp to bar.cpp
- add a string to size_with_unit converter
- add point support (with pt)
- add pixel support (with px)

* Fix unit test compilation

* clang-format

* Better names

The old names didn't really capture the purpose of the structs and
function.

space_type -> spacing_type
space_size -> spacing_val

size_type -> extent_type
geometry -> extent_val

geometry_format_values -> percentage_with_offset

* Remove parse_size_with_unit

No longer needed. The convert<spacing_val> function in config.cpp
already does all the work for us and always setting the type to pixel
was wrong.

In addition, line-size should not be of type spacing_val but extent_val.

* Cleanup

I tried to address most of my comments on the old PR

* Fix renderer width calculation

We can't just blindly add the x difference to the width because for
example the width should increase if x < width and the increase keeps
x < width.

Similarly, we can't just add the offset to the width.

* Rename geom_format_to_pixels to percentage_with_offset_to_pixel

* Cleanup

* Apply suggested changes from Patrick on GitHub

* config: Use stod for parsing percentage

* Use stof instead of strtof

* units: Fix test edge cases

* Remove unnecessary clang-format toggle

* Use percentage_with_offset for margin-{top,bottom}

* Support negative extent values

* Rename unit to units and create a cpp file

* Move percentage_with_offset_to_pixel unit test to units

* Add unit tests for units_utils

* Clarify when and how negative spacing/extent is allowed

Negative spacing is never allowed and produces a config error.

Extents allow negative values in theory, but only a few use-cases accept
it.
Only the extent value used for the `%{O}` tag and the offset value in
percentage_with_offset can be negative. Everything else is capped below
at 0.

The final pixel value of percentage_with_offset also caps below at 0.

* Fix parsing errors not being caught in config

* Print a proper error message for uncaught exceptions

* Cleanup module::get_output

All changes preserve the existing semantics

* Stop using remove_trailing_space in module::get_output

Instead, we first check if the current tag is built, and only if it is,
the spacing is prepended.

* Remove unused imports

* Restore old behavior

If there are two tags and the second one isn't built (module::build
returns false), the space in between them is removed.
For example in the mpd module:

format-online = <toggle> <label-song> foo

If mpd is not running, the mpd module will return false when trying to
build the `<label-song>` tag. If we don't remove the space between
`<toggle>` and `<label-song>`, we end up with two spaces between
`<toggle>` and `foo`.

This change is to match the old behavior where at least one trailing
space character was removed from the builder.

* Add changelog entry

* Remove unused setting

* Use percentage with offset for tray-offset

patrick96 3f03b671bb fix(color): Rename type() function to get_type
In gcc5, this caused compilation errors because the type enum has the
same name.

New Tag Parser (#2303)
* refactor(color): Use enum class for color type

* Add testcases for tag parser

* Make tag parser a pull-style parser

Being able to parse single elements at a time gives us more fine-grained
error messages, we can also parse as much as possible and only stop
after an exception.

* fix(color): Parser did not check for invalid chars

* tag parser: First full implementation

* tag parser: Fix remaining failing tests

* tag parser: Replace old parser

* tag parser: Treat alignment as formatting tag

Makes the structure less complex and the alignment tags really are
formatting tags, they are structurally no different from the %{R} tag.

* tag parser: Cleanup type definitions

All type definitions for tags now live in tags/types.hpp, the parser.hpp
only contains the definitions necessary for actually calling the parser,
this shouldn't be included in many places (only places that actually do
parsing). But many places need the definitions for the tags themselves.

* Rename components/parser to tags/dispatch

* tag parser: Cleanup

* Add changelog

fix(builder): Properly apply alpha for fg and bg
It was not quite clear how try_apply_alpha should behave if the given
color was not ALPHA_ONLY. The implementation just returned 'this'.
However, the build relied on it returning the given color.

This broke all bg and fg settings in the entire bar.

To clear this up, we switch this around take the alpha channel of 'this'
and also return 'this' if it isn't ALPHA_ONLY.

Fixes #2255

patrick96 53c6f3b042 refactor(color): Better channel function names
(alpha|red|green|blue)_(d|i) are used for the four channels using
doubles or integers, respectively.

patrick96 8e10c046fa Move all channel functions into rgba class
Since we use rgba everywhere, extracting channels from uint32_t directly
is not necessary anymore.

patrick96 64fa6469ab Remove unused hex function
This allows us to also remove the cache class which was only used here

patrick96 b238ec3403 Move most color_util functions into rgba class
The intent is for every color to be stored in a rgba instance

The rgba class now stores the color in a 32 bit integer to save space

This also removes the unused class rgb and moves everything else into a
cpp file.

Many functions also had weird template parameters. For example
alpha_channel<unsigned short int> would give a 2 byte number with the
alpha channel byte in both bytes.
color_util::hex would return a hex string with alpha channel if unsigned
short int was given and without if unsigned char was given. Even more
curiously those parameters were passed to *_channel and the result
nevertheless truncated to 8bits.
