Gerhard Sittig 88a5f9eabe asix-sigma: improve error propagation, increase robustness
Detect more error conditions, and unbreak those code paths where wrong
data was forwarded. It's essential to tell the USB communication layer,
sigrok API error codes, and glib mainloop receive callbacks apart. Since
the compiler won't notice, maintainers have to be extra careful.

Rephrase diagnostics messages. The debug and spew levels are intended
for developers, but the error/warn/info levels will get presented to
users, should read more fluently and speak from the application's POV.
Allow long text lines in source code, to not break string literals which
users will report and developers need to search for (this matches Linux
kernel coding style).

This commit also combines the retrieval of sample memory fill level,
trigger position, and status flags. Since these values span an adjacent
set of FPGA registers. Which reduces USB communication overhead, and
simplifies error handling. The helper routine considers the retrieval
of each of these values as optional from the caller's perspective, to
simplify other use cases (mode check during acquisition, before sample
download after acquisition has stopped).

INIT pin sensing after PROG pin pulsing was reworked, to handle the
technicalities of the FTDI chip and its USB communication and the FTDI
library which is an external dependency of this device driver. Captures
of USB traffic suggest that pin state is communicated at arbitrary times.

README

-------------------------------------------------------------------------------
README
-------------------------------------------------------------------------------

The sigrok project aims at creating a portable, cross-platform,
Free/Libre/Open-Source signal analysis software suite that supports various
device types (such as logic analyzers, oscilloscopes, multimeters, and more).

libsigrok is a shared library written in C which provides the basic API
for talking to hardware and reading/writing the acquired data into various
input/output file formats.


Status
------

libsigrok is in a usable state and has had official tarball releases.

While the API can change from release to release, this will always be
properly documented and reflected in the package version number and
in the shared library / libtool / .so-file version numbers.

However, there are _NO_ guarantees at all for stable APIs in git snapshots!
Distro packagers should only use released tarballs (no git snapshots).
