6898a9dcf1 Do not localize configuration options
The configuration options shown in the configuration menu are meant to
reflect the keys used in the configuration file. The descriptions
displayed alongside each option should be sufficient for non-English
speakers.

cfd8ede2b3 Switch to Linux kernel coding style
Convert our code base to adhere to Linux kernel coding style using
Lindent, with the following exceptions:

* Use spaces, instead of tabs, for indentation.
* Use 2-character indentations (instead of 8 characters).

Rationale: We currently have too much levels of indentation. Using
8-character tabs would make huge code parts unreadable. These need to be
cleaned up before we can switch to 8 characters.

6c11b8985c Fix data type of "general.firstdayofweek"
This option wasn't converted to a proper data type when it was renamed
from "week_begins_on_monday" to "general.firstdayofweek". Convert the
boolean option into an enumeration type that can take the values
"monday" and "sunday". Also, update the documentation, add a conversion
rule to the upgrade script and convert the configuration file used in
the test suite.

6da787a5cc Declare several parameters/variables constant
Add the "const" keyword to parameters and variables that are never
modified. Most of these were spotted by "-Wwrite-strings".

We cast the second parameter to execvp() explicitly as it expects a
"char *const[]" where it should expect a "const char *const[]"
(according to the documentation, this is due to compatibility reasons).
This should be changed once we come up with a better solution.

c85c3cce55 Fix semantics of "general."{systemdialogs,progressbar}
These were renamed from "skip_"* to *. However, we only changed syntax
and didn't invert their semantic meaning. Fix this by negating the
semantics of those variables. Also, negate these in the configuration
file automatically when running `calcurse-upgrade`.

b5c1981842 Revamp key bindings display
Refactor the logic inside keys_display_bindings_bar() and remove the
need to place the "show next page" key binding at the right positions.

This used to be a pain to maintain, since we always had to move key
bindings around when introducing a new key. Fix this by passing the
actual key bindings in an array and using a separate parameter for the
"show next page" key binding (which is automatically inserted at the
right places from now on).

7cc6305588 Do not cast unused return values to void
A small style fix that removes all remaining "(void)" casts. Using these
isn't encouraged in GNU coding guidelines and doesn't serve a certain
purpose, except for satisfying a few static code analysis tools. We
already nuked some of these in previous patches, but this semantic patch
should fix what's left:

44bc9605d6 Avoid use of printf()/fprintf()
Use one of the following functions where appropriate:

* puts() (whenever we print hard coded strings to stdout)
* fputs() (whenever we print hard coded strings to a stream)
* putchar() (whenever we print a single character to stdout)
* fputc() (whenever we print a single character to a stream)
* strncpy() (whenever we copy hard coded strings to a buffer)

This removes the overhead introduced by the format string parser and
reduces the number of false positive C-format strings spotted by
xgettext(1)'s heuristics.

This one came up after improving resizing behaviour in commit
fec37db06bbbdff79bc9816046a76e0b29e173b4. We used to use outdated width
and height values at various places without noticing it due to the
resize algorithm being called several times on every resize.
