Add support for combined date/time or date-only strings when specifying
the start or end time of a new item.

According to the iCal standard (4.3.12 Time):
UTC time, or absolute time, is identified by a LATIN CAPITAL LETTER
Z suffix character (US-ASCII decimal 90), the UTC designator,
appended to the time value.
Parse such time values properly when importing iCal files.
Fixes GitHub issue #3.

Avoid preallocating buffers on the stack, use dynamic memory allocation
instead. Also, change the semantics of new_tempfile() so that it returns
the full name of the temporary file and fix all call sites.

Use asprintf() in some cold code paths. While allocating memory on the
heap is a bit slower, using asprintf() is a bit more memory efficient
and less prone to buffer overflow errors.
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
The new utils.c functions vasprintf() and asprintf() are analogs to
sprintf() and vsprintf(). However, instead of requiring a buffer that is
large enough to hold the output data, the functions allocate a string
and return a pointer to it.

This complete rewrite of the scroll window implementation decouples
scroll windows from every other window abstraction layer we use. Note
that this leads to some code duplication. The long-term purpose of this
rewrite, however, is to eventually make every panel use scroll windows.
This makes for a huge cleanup of the UI code.

After BUG#6 had apparently been closed with the screen locks introduced
in commit a80f8dcf2c6eb3b54658218bc081ee9694204dd5, some people still
had problems with random characters appearing in the notification bar.
This was obviously caused by wgetch() refreshing the screen if the
status panel was changed. From wgetch(3):
If the window is not a pad, and it has been moved or modified since
the last call to wrefresh, wrefresh will be called before another
character is read.
Since the wgetch(3) isn't thread-safe, there were race conditions
between the notification bar thread drawing to the notification bar and
wgetch() updating the screen. Introduce a (hidden) window that handles
all key presses and never gets changed in order to avoid this.
Also, call wins_wrefresh() explicitly in status_mesg(), since we can no
longer rely on wgetch() updating windows automatically.
Fixes reopened BUG#6. Note that this is a hotfix -- FR#26 has been
opened to ensure we fix this properly in the next major release.

Since the result of localtime() is stored in a statically allocated
structure, data was overwritten when a context switch occurred during
(or shortly after) the execution of localtime(), potentially resulting
in critical data corruption. BUG#7 and BUG#8 are likely related.
This patch converts all usages of localtime() with localtime_r(), which
is thread-safe.

This adds support for vim-style copy/paste registers which allows
cutting and copying multiple items without having to overwrite the
copy/paste buffer. Registers can be specified using the quote key ('"').
To access a register, type '"x' before a command where "x" is the name
of a register. If you want to copy the currently selected item into
register 1, type '"1c'.
Valid registers are 0-9, a-z, "-" and "_". Note that the latter is the
so-called black hole register, which works similar to the black hole
register in vim.
The register prefix key is currently hardcoded and cannot be configured.
