Gerhard Sittig 9b915e3a41 scpi: document callers' responsibility to free getters' allocated memory
Some of the SCPI getter routines allocate memory for response data which
callers need to free after use. Document this responsibility in more
places, and rephrase existing locations for consistency. See a word-diff
for the essence of the commit.

It's assumed that the separate paragraph in the function description is
better perceived than something that's hidden in the parameter or return
value discussion. Also reference the corresponding free routine by name
for callers' convenience (data types will differ among routines). Some
free routines can be called unconditionally, others require NULL checks
at the caller's.

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).

------------

Requirements for the C library:

 - git (only needed when building from git)
 - gcc (>= 4.0) or clang
 - make
 - autoconf >= 2.63 (only needed when building from git)

Device-specific issues
----------------------

Please check README.devices for some notes and hints about device- or
driver-specific issues to be aware of.


Firmware

Some devices supported by libsigrok need a firmware to be uploaded before the
device can be used. See README.devices for details.
