Wolfram Sang a66175c2b1 input: vcd: avoid needless copying
Current code moves the identifier string one byte to the front to
overwrite the bit value, so 'tokens[i]' is a string to compare against
the desired value. This copying is unnecessary, just pass a properly
setup pointer.

Wolfram Sang 76bc28c3f1 input: vcd: try to continue when a vector was found
No need to bail out on vectors. As long as there are tokens left, we can
try to parse the rest. Also, print a message so the user knows what's
going on. Here is a testcase vcd:

$timescale 1 ns $end
$var wire 1 n0 addr_0 $end
$var wire 1 n1 addr_1 $end
$enddefinitions $end
#0
0n0
b1 n1
#1
1n0
b0 n1
#2
0n0
b1 n1

Wolfram Sang 73f052d329 input: vcd: properly bail out on missing identifiers
If we hit the missing identifier case, then we reached the end of the
token list. So, we should break out of the loop, and not continue.
Otherwise we will go past the end of the array as this minimal testcase
shows:

$timescale 1 ns $end
$var wire 1 n0 addr_0 $end
$enddefinitions $end
1

gives:

$ ./sigrok-cli -I vcd -i no_mod.vcd -O vcd -o /tmp/o.vcd
Segmentation fault

Wolfram Sang e85e550d92 input: vcd: allow optional index item
A $var block can have an optional index item which looks like '[<sth>]'.
Parse it, too, and append it to the channel name.

This fixes bug #322. A first version was posted by Simon Richter. This
version is rebased and simplified.

Petteri Aimonen db0e5c999d VCD input: Chunk up the samples in 1MB blocks.
This gives about 100x speed improvement when converting VCD->SR.

Also should allow practically unlimited number of channels.

This fixes bug #551.

This fixes various compiler warnings when -Wdiscarded-qualifiers is used.

Daniel Elstner 6ec6c43b47 Build: Include <config.h> first in all source files
Since Autoconf places some important feature flags only into the
configuration header, it is necessary to include it globally to
guarantee a consistent build.

Daniel Elstner c1aae90038 Build: Set local include directories in Makefile.am
Move the include flags for files in the source tree from
configure.ac to Makefile.am where they belong.  Also use
AM_CPPFLAGS instead of CFLAGS/CXXFLAGS to make sure the
files in the build/source tree are always picked up first.

Also, remove the include/libsigrok sub-directory from the
search path, thereby making the <libsigrok/> prefix mandatory
when building libsigrok itself.  This matches the convention
already imposed on users of the library.

Martin Ling 5e23fcab88 Simplify channel creation.
We always follow sr_channel_new() with a call to add the channel to the sdi.
Tidy up a bit by adding this functionality to sr_channel_new() instead.

Aurelien Jacobs 73931b7cc7 input/vcd: fix parse_header() return value check.
Mixing tests for both a boolean and an SR_ERR at the same time is not
really a good idea.
parse_header() actually returns a boolean so only check if it returns FALSE.

This fixes the following gcc-5 warning:

src/input/vcd.c: In function 'receive':
src/input/vcd.c:506:34: warning: logical not is only applied to the left hand side of comparison [-Wlogical-not-parentheses]
   if (!parse_header(in, in->buf) != SR_OK)

Bert Vermeulen d5cc282ff8 input: sr_input_free() is now a void function.

Bert Vermeulen 7066fd4660 input: Add sr_input_end().
This signifies to the module instance no more input will come. This
will cause the module to process any data it may have buffered. The
SR_DF_END packet will also typically be sent at this time.

Bert Vermeulen d018181331 input: Add sdi_ready flag to struct sr_input.
When an input module instance has received enough input to fully
populate the struct sr_dev_inst, sdi_ready is set to TRUE and its
receive() method returns immediately. Any remaining received data
is buffered until the next time the function is called.
