Alexandru Gagniuc a99e0d2a0c ols: Do not randomly probe serial ports
ols driver used to probe a series of available serial ports obtained
by regexp matching of common serial port names.
There are a number of problems with this approach:
1. It will probe all serial devices, including devices that do not
like to be probed, potentially causing them to act up.
2. It will try to probe serial ports which may already be opened in
other applications for other purposes.
3. It assumes the naming of the serial ports is set in stone, and
creates an unnecessary OS-specific list.
4. It produces unnecessary debug output even when an OLS device is
not connected.
5. etc...

Do not implicitly probe serial ports. Only probe the port specified
by the frontend, if any; otherwise, just quit.
Also get rid of all functionality in serial.c which was designed
specifically for random probing.

Uwe Hermann 8c1adf3738 Rework FS9721 parser.
Merge parts of the tekpower-dmm code (the chip of the TekPower
TP4000ZC seems to be an FS9721_LP3 too) and rework parts of the functions.

Adapt the tekpower-dmm and uni-t-dmm code accordingly.

Uwe Hermann 6c701476ad Add protocol parser for FS9721_LP3/FS9721B.
The Fortune Semiconductor FS9721_LP3 and FS9721B/Q100 DMM chips are very
similar and the protocol looks identical.

Tested on a Voltcraft VC-820 (FS9721_LP3) with the uni-t-dmm driver
(needs some small changes, tbd).

All frontends will have to include <libsigrok/libsigrok.h> from now on.
This header includes proto.h and version.h, both installed from the
distribution into $INCLUDE/libsigrok/ as well.

The only dynamically changed header is now version.h, which has both
libsigrok and libtool compile-time versions in it.

Uwe Hermann 133a37bfba Use g_try_malloc/g_free/g_strdup consistently.
Avoid plain malloc()/free() in sr/srd, especially in the API calls.
Also avoid g_malloc*() in favor of g_try_malloc*().

Use g_strdup() instead of strdup() so that we can use g_free()
consistently everywhere.

Exceptions: Stuff that is allocated via other libs (not using glib),
should also be properly free'd using the respective free-ing function
(instead of g_free()). Examples: Stuff allocated by libusb, libftdi, etc.

Also, use sr_err() instead of sr_warn() for actual errors. sr_warn() is
meant for non-fatal/uncritical warnings.

Uwe Hermann 1a081ca67d sr: Mark API functions with SR_API/SR_PRIV.
Use SR_API to mark public API symbols, and SR_PRIV for private symbols.

Variables and functions marked 'static' are private already and don't
need SR_PRIV. However, functions which are not static (because they need
to be used in other libsigrok-internal files) but are also not meant to
be part of the public libsigrok API, must use SR_PRIV.

This uses the 'visibility' feature of gcc (requires gcc >= 4.0).

Details: http://gcc.gnu.org/wiki/Visibility

Uwe Hermann b7f09cf86d libsigrok: Fix #includes.
In the lib, we should only #include "sigrok.h" or "sigrok-internal.h",
but not the (possibly installed and thus different/older versions) via
<sigrok.h> or <sigrok-internal.h>.

Frontends should of course use <sigrok.h> and <sigrok-internal.h>.

Uwe Hermann a0ecd83bc6 Make more variables/functions static and non-global.
The 'GSList *devices' from device.c was actually really global (i.e.,
listed in sigrok.h), which is now fixed.

Bert Vermeulen e10d6e32e4 saleae-logic: support for other FX2 devices (bare FX2)
This enables support for devices that have a different VID/PID
than the Saleae Logic, and yet another after firmware upload.

After firmware upload is checked every 100ms whether it came back,
instead of always waiting for 2 seconds.

If the kernel attaches a driver to a device we know, detact it first.

Uwe Hermann 548b08e55c Drop unneeded skeleton files.
They're not too useful as they mostly consist of a list of function names,
and that list is already available in the respective struct. The wiki
API docs and the code in the various hardware/output drivers serve as
useful examples already, no need for additional files.

Uwe Hermann b08024a836 libsigrok: Introduce sr_dbg/sr_info/sr_warn/sr_err.
We should use these (internal) functions in libsigrok exclusively from
now on, i.e. no more use of glib's g_debug() etc.

These functions are only for libsigrok, the frontends use whatever
logging mechanism is suitable there.

Uwe Hermann 340f6e7aea Fix out-of-tree build.
Use libtool "noinst" local helper libs and use one Makefile.am per
subdir, which is the usual/preferred method. These helper libraries are
purely local and will not be installed.

This also fixes out-of-tree builds of sigrok, i.e. building in a
directory other than the sigrok source directory, e.g.

 $ cd /home/user
 $ git clone ...sigrok
 $ cd sigrok
 $ ./autogen.sh
 $ mkdir /tmp/foo
 $ cd /tmp/foo
 $ /home/user/sigrok/configure
 $ make
 $ make install

This will place all build results (.o files, .la files, etc) in the
local build directory (/tmp/foo) instead of the source directory
(/home/user/sigrok in this example). The installation directory is
selected via the --prefix configure option (/usr/local per default).
