The configuration file (~/.calcurse/conf by default) can now be
specified with -C or --conf.

The pre-load hook is often used to manipulate the data files before
loading, such as by synchronizing with a remote calendar. Make sure we
always execute the pre-load hook upon reloads, even if the data files
have not been modified.
Fixes GitHub issue #98.

When running calcurse in non-interactive mode, we should not expect any
user input. This is even more important in the case of iCal imports
which are used by calcurse-caldav to import events from CalDAV servers.
Partly fixes GitHub issue #73.

After resolving a save conflict with the merge tool, we need to reload

After saving the data files, we need to recompute and store the hashes
to make sure the updated contents is reflected.

Replace the save mutex with a common mutex, which is locked whenever
read or write operations on the data files are performed. Also, since
this mutex is an implementation detail, mark the locking functions
static and remove them from the header file.

Instead of blindly reloading data in io_reload_data(), compare the
stored hashes of the data files with hashes of the current file contents
and only reload if any of the hashes differs.
Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
Move the check to compare the stored hashes of the data files with the
current hash to a separate function. This makes the code easier to read
and reusable.

When reading the data files, compute a cryptographic hash of the file
contents and store it. When saving the files later, ensure that the hash
still matches the current file contents. If it does not, show a warning
to the user and ask whether she wants to execute the merge tool.

Using the file name extension .sav and naming the variables "backup" is
slightly misleading, since the affected files actually contain the
updated content and not some old snapshot. Use the term "new" instead.

We need to manually force a reinitialization of the todo item list box
before reloading the items. Otherwise, the list box contains dangling
references to the linked list of todo items which has already been
cleared at this point. After the pre-load hook is called, the windows
are redrawn by wins_unprepare_external() and these invalid references
are accessed, leading to a segmentation fault.

In commit 3eae7ce (Add --list-imported command line option, 2016-01-12),
we added an option to print the hashes of imported items to stdout.
Extend this command line option such that it dumps the items using the
specified formatting strings. With the new behavior it is, for example,
easier to check items for import errors.
Also, rename the option from --list-imported to --dump-imported (it is
not part of any official release yet so we do not need to care about
backwards compatibility).

This adds support for hooks which are executed before/after saving
calcurse data. Hooks can be placed under hooks/pre-save and
hooks/post-save in the data directory and need to be executable.
Potential use cases include:
* Automatically commit any changes to the data files using a VCS.
* Automatically sync with some sever component on data file changes.
