7fe240856e Flush the output stream instead of arbitrarily disabling buffering
This is (arguably) more elegant and it matches Xlib output logic.
Also use puts instead of printf as we don't do formating there.

81d5b427cb Don't explicitly list each component-target
I made a mistake while reading the Posix spec. In fact, the implicit
prerequisite imposed by the .c.o-rule is evaluated as expected, even if
the .c is not given in the target rule.

This partially reverts 0efd64ffaa.

a18439af11 Refactor swap.c to use getline() instead of buf-filling
This drops a lot of code and even though we are using a common function,
the specification of only the needed things keeps it very efficient and
even more efficient in memory and time than the previous solution.

0efd64ffaa Explicitly list component-objects in the Makefile
There was a long tinkering process at farbfeld about this, but the sad
truth is that it's the only way to make the Makefile truly portable.
Listing it just as

   $(COM:=.o): config.mk $(REQ:=.h)

omits the dependency on the c-file itself, which incurs that strictly
speaking the object file is not depending on the source file, which is
nonsense.

You don't see strictly Posix compliant Makefiles around very often and
most use nasty GNU-extensions everywhere. It is a good idea to go ahead
as a fitting example and show how to write them portably.

c28643ce5b Revert "Add basic backlight percentage support"
On OpenBSD the backlight percentage cannot be retrieved in a simple way.
The only two solutions we are aware of for now are:

 - reading from /dev/ttyC0: which isn't possible without changing
 permissions or running slstatus as root
 - linking against xcb-xrandr: which is bloat and does not work in every
 case appearently

This reverts commit 37724ac2c3 for now.

f17f39d0a2 Refactor keymap.c
- Get rid of camel-casing
 - Don't use all-caps for variable names
 - use LEN()-macro
 - use strncmp() rather than strstr() for prefix-checking
 - clean up the tokenizer-loop and don't use copies
 - make the loop more readable by separating different breaking
   conditions
 - stricter error-checking and cleanup
 - store the layout directly with bprintf rather than having
   a separate buffer

943b42de05 Add keymap component
Adding a new keymap component that will
indicate the current keyboard layout (language)
and variant if any was set. I use the
standard X11 XKB APIs to retrieve and parse
the xkb_symbols set with setxkbmap.

57f69e900b Remove o-flag as it is redundant
Even if we extend the flag to be an n-flag with a numerical input, we
already have other Unix-tools to take care of us much more flexibly,
e.g. with head(1) you can easily get the first 10 outputs with

	slstatus -s | head -n 10,

but also e.g. discard the first one and then get the consecutive 10
outputs.

For the X11-root-window-name, you can limit the runtime with timeout(1)
or a comparable solution.

This reverts commit fa8b939990.

9c9ce8a125 Check printf() for output errors
This way cases like

	$ slstatus -s > /dev/full

are properly caught and the program terminated with the proper return
code.

when there has been a critical error instead of carrying on uselessly.

ceb13206a4 Refactor fmt_human() and fix a bug
It is not necessary to copy memory or anything. Just keep a pointer to
the active prefix-array and assign the length of the arrays to a
variable.

Make the code more readable by using a switch, be more strict when an
invalid base is passed to it and fix a small oversight in the bottom of
the code where the base 1024 was forgotten to generalized.

ec5c35ec9f Remove units from numbers
This is a first step to decouple formatting from information because of
two reasons:

 1. The components should only gather and return the values by design
 2. Fine grained user control should be a focus

Scaling will be implemented in a different way in a later commit.

f386a03a20 Support energy_now/power_now in battery_remaining
On some laptops (mostly thinkpads), the remaining time may be
expressed in µWh using energy_now and power_now files rather than µAh
for charge_now and current_now.

Add pick function to conditionally select appropriate one.

46c4540dd2 Implement fmt_human_2() and fmt_human_10()
These functions take the raw number and a unit and automatically
print it out "scaled down" to a proper SI-prefix, for powers of 2
and 10 respectively.

Apply them to the 2-power cases and keep the 10-power for a later
commit.
