When we only want to display a string at a specific place of the
screen, there's no need to use the more complex mvwprintw(), use
mvwaddstr() instead.
This should be slightly more efficient, and, above all, it prevents
weird things to happen if our string contains a '%', being interpreted
as an unwanted format string.

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.

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.

Be consistent and replace the custom linked list implementation we used
here by the generic list implementation we use everywhere else. This
reduces code complexity, while slightly improving memory overhead.

All strncmp() usages were replaced by (evidently) equivalent strcmp()
invocations in commit 2c9499bf272e06a62902711c6c20621ef3f80e64. However,
some of the strncmp() calls were perfectly justified and we actually
broke iCal import and "C-"-style key bindings by converting them to
strcmp(). Fix this by reverting all affected conversions.

These were only used to construct constant strings with additional
length fields. However, we can just use standard constant character
arrays instead and let the compiler calculate the string length.

strncmp() isn't intended to be a secure strcmp() replacement, it is
designed to be used if you want to compare the first n characters of two
strings. Since we always compare character pointers with string
literals, switch to using strcmp() everywhere.

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).

The bzero() and bcopy() functions are deprecated and were removed from
the POSIX standard in IEEE Std. 1003.1-2008. Remove all usages of
bzero()/bcopy() and replace them by appropriate memset()/memmove()
calls.

The last argument to strncat() should not be the total buffer length; it
should be the space remaining:
The strncat() function shall append not more than n bytes (a null
byte and bytes that follow it are not appended) from the array
pointed to by s2 to the end of the string pointed to by s1. The
initial byte of s2 overwrites the null byte at the end of s1. A
terminating null byte is always appended to the result.
This patch fixes a couple of potential buffer overflow vulnerabilities.

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:

identifier func;

- (void)func (

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.

Key descriptions are just strncpy()'ed to key[], with KEYS_KEYLEN as
maximum character count. This leads to a non-null-terminated string if
the source pointer actually points to a string with a length of
KEYS_KEYLEN bytes. Always appending a null character fixes this.
