38726c5906 Always use stdout via output proxy
The switching between stdout and stderr on an automated basis caused
errors in the using code, where output was redirected but shouldn't.

542c7e7101 Make stdin always available
Because we do not implement the store piping and pipe magic, the stdin
stream should always be available.

d7cfab797f Revert "Implement pipe magic in libimagrt"
This reverts commit ce0bd9298a.

Pipe magic is removed with this patch.

We remove pipe magic because its implementation in libimagstore is too
complicated and the benefits are too small.
Having this functionality would be really nice, but the cost-benefit
ratio would still be too high.
The implementation in the store would require a rewrite of the internal
caching functionality in the store, plus some functionality to serialize
and deserialize the cache. This is theoretically possible, but as the
store only knows about "StoreEntry" objects, and only the backend knows
of "Entry" (which would be simply de/serializeable), the complexity
increases a _lot_.

Hence, we drop this feature-idea here.

Maybe, at some later point, this functionality will be in imag. The
history of development of this feature is in the history, we just don't
have it merged.

c5c9c7b9ba Fix: Editor commands should be split at whitespace
This fixes the following problem:

If the editor setting was "vim " instead of "vim", the editor was called
with `"vim" " "`, which resulted in unexpected behaviour.

Implement pipe magic in libimagrt

ce0bd9298a Implement pipe magic in libimagrt
When we merged the changes in libimagrt so that it automatically detects
whether stdin/stdout is a TTY and provides the user with stderr in case
stdout is not a TTY, we forgot that things like

    imag foo | grep bar

becomes impossible with that, because imag detects that stdout is not a
tty and automatically uses stderr for output.

But in this case, we don't want that. The output has to be stdout in
this case.

With this change, we have a flag in the runtime ("--pipe-magic" or "-P",
globally available) which turns on "pipe magic".

The expected behaviour is the following, if "-P" is passed:

* If stdout is a TTY, we print to stdout
* If stdout is not a TTY, we print to stderr
* If stdin is not a TTY, we do not provide it

If "-P" is not passed, we allow the user of libimagrt to use stdin for
interactive stuff (the interactive stuff is not yet implemented).

da408b9e67 This fixes the file parsing (again)
Unfortunately, our latest fix to file parsing did not solve all issues.
So we have to fix it _again_.

The problem was the `std::str::Lines` iterator, which apparently fails
this:

    assert_eq!(1, "".lines().count());

as an empty line seems not to be a line.

Because of that, when reading a file with an empty line at its bottom
got stripped off that line.

This patch removes the use of the `lines()` iterator and uses
`split("\n")` instead. This only works on Unix operating systems, but as
we only target unix operating systems with imag, this is not considered
an issue right now.

This patch also adds extensive tests on multiple levels in the
`libimagstore` implementation:

* On the parsing level, for the function which implements the parsing
* On the filesystem abstraction levels
* On the `Store` levels

to make sure that everything is parsed correctly.

19e9dfe33c Implement proxy object where runtime configures output
This is another approach for providing access to stdin/out/err via
libimagrt::runtime::Runtime.

The Runtime object does configure which output gets returned (stdout if
stdout is a tty, else stderr).

With this we can change libimagrt to read/write the store from/to
stdin/stdout without the user noticing that she does not write to stdout
but stderr.
Reading from stdin is not possible then, though.

c18c0bbbe4 Provide stdin/out/err resources via Runtime object
This way we can control whether "out" output goes to stdout or stderr
without the user of the functionality knowing.

This is useful for later when we use libimagrt to automatically
read and write the store from and to stdout/in depending on whether we
are talking to a TTY or a pipe.

Rewrite entry parsing algorithm

9fb5f453fe Rewrite entry parsing algorithm
Rewrite without regex crate.

The regex approach was broken. If the following _content_ was provided
in the entry:

    foo

    ---

    bar

The regex approach parsed the header until the "---" in the content.
This is, of course, not the way to do that.

Now, the parsing is implemented by hand. Should be faster as well,
though I don't care about this.

This fixes a severe bug.
