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.

7f91ce265e swap.c: Refactor getstats() and its usage 
Add a return value so we are able to check any errors and actually fail
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.

10dbc9543e Merge fmt_human_2 and fmt_human_10 to one function 
Now only one function, fmt_human, takes an additional argument "base".

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.

68a3902dc5 Increase precision in netspeeds.c 
First dividing by interval before multiplying with 1000 decreases the
precision by +-(interval - 1) * 1000, as interval arithmetic always
applies the Gauß-function to the result.

This is not necessary and simply reordering the operations mitigates
this.

422cadfd5f Implement esnprintf() and make formatted calls more efficient 
Within the components, snprintf() was unchecked and had inefficient
calls in some places.
We implement esnprintf() that does all the dirty laundry for us
and use it exclusively now.
