The last release (0.4.0) had the libtool version (current:revision:age)
set to 3:0:0. Since this release adds, removes, and changes interfaces,
the new version is 4:0:0.

This changes the library filename (e.g. on Linux) from libsigrok.so.3.0.0
to libsigrok.so.4.0.0, the SONAME (+symlink) becomes libsigrok.so.4.

This fixes bug #857.
(the XML file is moved from PulseView to libsigrok since this is not
PulseView-specific)
Add a 48x48 PNG and a scalable SVG for the MIME type as well.
Install the XML file and in the icons in the respective standard paths.
This is more specific and prevents any potential issues e.g. when
multiple distro packages might ship with a generic file like
sigrok-logo-notext.png that's supposed to be installed in the same place.
The Input::send() method allocated glib strings and copied input data,
but only released the glib string container and leaked the actual string
content. This led to leaks in the size of the verbatim input file, which
is especially wasteful for uncompressed textual representations.
This fixes bug #976.
When the processing of columns of text lines detected errors, the loop
was aborted and the routine was left, but allocated resources were not
freed. Fix the remaining memory leaks in the error code paths.
The constant at the top of the source file is the number of samples in a
datafeed submission chunk. The previous implementation erroneously made
it the size in bytes. There is no need to round down the buffer size
according to the unit size.
The previous implementation sent one sigrok session datafeed packet per
processed CSV line. This is rather inefficient for the CSV input module,
and triggers a dramatic performance loss in the srzip output format.
Communicate up to 128K samples within one datafeed packet. This fixes
bug #695.
Factor out repeated calculation of the unit size which is derived from
the channel count. Fix a minor memory leak in an error path while we are
here. (Other memory leaks in rare error paths remain with this commit.)

On the Windows platform it appears to be popular to _not_ terminate the
very last line in a text file. Which results in an unmet constraint in
the CSV input module and an internal exception in PulseView which aborts
program execution.
Cope with the absence of the text line termination sequence at the very
end of the input stream. Keep all other checks in place, such that only
completely received text lines get processed.
This fixes bug #635.
"Document" the current state of the implementation in the CSV input
module's source code. Discuss how text handling is non-trivial, which
approaches are available and how they have drawbacks.
Mention the lack of support for the import of analog data as well.
The CSV input module supports variable length end-of-line encodings
(either CRLF, or CR, or LF). When a bunch of accumulated text lines got
processed, do skip the corresponding number of characters after the end
of the last processed line.
This fixes one of the issues discussed in bug #635.
The input module runs receive() and end() invocations which end up
calling process_buffer(). It's perfectly legal to call the process
routine with an empty accumulation buffer, especially when the process
routine was called from end().
This fixes a condition where PulseView raised a fatal error at the end
of a completed successful import.

Move an independent test for single/multi column operation out of a code
path that checked for and then processed text lines. This commit does
not change behaviour, but prepares a subsequent commit.
Factor out a magic string literal which held a delimiter set yet could
be mistaken for an (assumed) fixed termination string. Concentrate the
determination of the end-of-line text encoding as well as the resulting
set of possible deliminters in one nearby location. The symbolic name
for the delimiter set eliminates the doubt on its purpose.
Change uninstall-local to uninstall-hook, since the latter is guaranteed
to run last (order is apparently not guaranteed for uninstall-local).
This fixes bug #861.
