The header is constructed lazily including line breaks, so just emit
the raw string as is.

We have to use fprintf instead of emit_line, because we want to emit the
tab after the color. This is important for ancient versions of gnu patch
AFAICT, although we probably do not want to feed colored output to the
patch utility, such that it would not matter if the trailing tab is
colored. Keep the corner case as-is though.

Add a new flags field to emit_diff_symbol, that will be used by
context lines for:
* white space rules that are applicable (The first 12 bits)
Take a note in cahe.c as well, when this ws rules are extended we have
to fix the bits in the flags field.
* how the rules are evaluated (actually this double encodes the sign
of the line, but the code is easier to keep this way, bits 13,14,15)
* if the line a blank line at EOF (bit 16)
The check if new lines need to be marked up as extra lines at the end of
file, is now done unconditionally. That should be ok, as
'new_blank_line_at_eof' has a quick early return.

In a later patch we want to buffer all output before emitting it as a
new feature ("markup moved lines") conceptually cannot be implemented
in a single pass over the output.
There are different approaches to buffer all output such as:
* Buffering on the char level, i.e. we'd have a char[] which would
grow at approximately 80 characters a line. This would keep the
output completely unstructured, but might be very easy to implement,
such as redirecting all output to a temporary file and working off
that. The later passes over the buffer are quite complicated though,
because we have to parse back any output and then decide if it should
be modified.
* Buffer on a line level. As the output is mostly line oriented already,
this would make sense, but it still is a bit awkward as we'd have to
make sense of it again by looking at the first characters of a line
to decide what part of a diff a line is.
* Buffer semantically. Imagine there is a formal grammar for the diff
output and we'd keep the symbols of this grammar around. This keeps
the highest level of structure in the buffered data, such that the
actual memory requirements are less than say the first option. Instead
of buffering the characters of the line, we'll buffer what we intend
to do plus additional information for the specifics. An output of
diff --git a/new.txt b/new.txt
index fa69b07..412428c 100644
Binary files a/new.txt and b/new.txt differ
could be buffered as
DIFF_SYMBOL_DIFF_START + new.txt
DIFF_SYMBOL_INDEX_MODE + fa69b07 412428c "non-executable" flag
DIFF_SYMBOL_BINARY_FILES + new.txt
This and the following patches introduce the third option of buffering
by first moving any output to emit_diff_symbol, and then introducing the
buffering in this function.

The emit_hunk_header() function is responsible for assembling a
hunk header and calling emit_line() to send the hunk header
to the output file. Its only caller fn_out_consume() needs
to prepare for a case where the function emits an incomplete
line and add the terminating LF.
Instead make sure emit_hunk_header() to always send a
completed line to emit_line().

As alluded to in the previous patch, the code in patch-ids.c is
using the hashmaps API wrong.
Luckily we do not have a bug, as all hashmap functionality that we use
here (hashmap_get) passes through the keydata. If hashmap_get_next were
to be used, a bug would occur as that passes NULL for the key_data.
So instead use the hashmap API correctly and provide the caller required
data in the compare function via the first argument that always gets
passed and was setup via the hashmap_init function.

When using the hashmap a common need is to have access to caller provided
data in the compare function. A couple of times we abuse the keydata field
to pass in the data needed. This happens for example in patch-ids.c.
This patch changes the function signature of the compare function
to have one more void pointer available. The pointer given for each
invocation of the compare function must be defined in the init function
of the hashmap and is just passed through.
Documentation of this new feature is deferred to a later patch.
This is a rather mechanical conversion, just adding the new pass-through
parameter. However while at it improve the naming of the fields of all
compare functions used by hashmaps by ensuring unused parameters are
prefixed with 'unused_' and naming the parameters what they are (instead
of 'unused' make it 'unused_keydata').
