481cb5524f Do not strncpy() strings returned by gettext()
Translated strings returned by gettext() are statically allocated.
There's no need to copy them to a buffer, we can use the pointers
returned by gettext() instead.

2c9499bf27 Use strcmp() instead of strncmp()
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.

03ed480654 Avoid redundant virtual screen updates
Remove some redundant wnoutrefresh() invocations. There's no need to
copy a window to the virtual screen unless doupdate() is invoked
immediately afterwards.

This reduces flicker when browsing in the calendar panel.

136e5bc4f7 Fix POSIX compliance
* "WAIT_MYPGRP" isn't POSIX'ish. Relying on this caused compilation
  issues in certain environments (e.g. under Cygwin). As a workaround,
  define "WAIT_MYPGRP" explicitly if it's undefined.

* "P_tmpdir" is an XSI extension. Don't try use it if it isn't
  available.

f77f4647d1 print_*(): Add format specifier to print notes
* Move print_notefile() from "src/args.c" to "src/utils.c".

* Add a "%N" format specifier to print_*(). This invokes
  print_notefile() and prints the content of an item's note file.

* src/args.c: Use the new format specifier instead of print_notefile()
  everywhere.

Add print_recur_apoint() and print_recur_event() helper functions to

these are only wrapper functions to print_apoint() and print_event()

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:

    @@
    identifier func;

    - (void)func (

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.
