i9e: Fix memory leak in clear_bottom_line().
In clear_bottom_line() we call readline's rl_copy_text() which
allocates a buffer for the given range of the current input line. But
we never free this buffer, which results in a memory leak. This patch
plugs the leak.

Handle empty command lines properly.
Both para_client and para_audioc create an argument vector from the
given command line using create_argv(). If the command line contains
only whitespace characters, this vector has length zero, and argv[0]
is NULL.
We missed to check for this at at least three places in audioc.c,
client.c and audiod_command.c, which resulted in crashes due to NULL
pointer dereferences or failed assertions.
These bugs can easily be triggered by starting para_client or
para_audioc in interactive mode, entering a single space character
and hitting return.
This patch adds the missing checks to prevent the crashes.

gui: Fix off-by-one in add_spaces().
Commit e90c6c0a (Speed up add_spaces().) changed add_spaces() to print
space characters in chunks rather than one at a time. It introduced
space[], an array of whitespace characters, which is written entirely
if there are more spaces to print than the size of the array. However,
in the calculation of how much was printed so far, we missed the fact
that sizeof(space) includes the terminating NULL byte, so this number
is in fact the number of space characters *plus one*.
Consequently, we printed too few space characters. This resulted in
parts of the previous string still being visible in the top window
of para_gui.

Provide "purpose" texts.
This text will be printed right after the program name in the --help

Each executable gets a purpose text, and for receivers, filters,
writers the purpose will be printed as part of the help output of
para_audiod, para_filter. para_recv and para_write.

Revamp ggo help.
This adds usage and description fields to struct ggo_help and
changes ggo_print_help() to optionally print these.
The boolean detailed_help flag of ggo_print_help() is replaced by a
bitmask which lets the caller specify what to print. Four pre-defined
masks are used to print the normal help, the detailed help, the help
for modules (receivers, filters, writers) and the detailed module help.
The new macro DEFINE_GGO_HELP can be employed to create a struct
ggo_help from a gengetopt structure.

Make gengetopt descriptions work.
With gengetopt's text and description options it is not possible to
print a text only when --detailed-help was given, but not when only
--help is given.
Moreover, headers generated with old versions of gengetopt do not
export the description text. However, declaring it unconditionally
causes compiler warnings on new systems.
To circumvent these problems, we introduce a new test for configure
which checks whether the description string is declared. If it is not,
we simply append the declaration to the *.cmdline.h files.
This change allows to move the description string of para_play to
the gengetopt source file.
Andre Noll [Fri, 12 Apr 2013 12:23:45 +0000 (14:23 +0200)]
Introduce version.c to limit recompilation on version changes.
Currently version.h includes git-version.h which changes whenever
a different commit is checked out or the working tree becomes dirty
because a file has been modified. Consequently, all .c files that
include this header must be recompiled in this case.
To limit the number of recompilations, this commit introduces
version.c, which contains functions that return the various types of
the version string. It is now the only file that includes version.h,
so only version.o must be rebuilt if git-version.h changes.
This also adds the build date, OS and CC version to the version output.
This difference comes from the fact that para_afh has its own
->print_help method which uses the VERSION_SINGLE_LINE macro of
version.h while para_audioc relies on gengetopt's help output.
The latter uses the make variable PACKAGE_VERSION which gets
initialized at configure time through the second argument in AC_INIT
of configure.ac. This value is either the version number for or the
string "git".
It's a good thing to have the abbreviated git version encoded in
all executables, so this commit changes the argument of gengetopt's
--set-version to the git version string including the codename. With
the patch applied, the output of all commands looks like this if
--version was given:
para_filter 0.4.12.12.g11d7 (spectral gravity)
To make sure things stay consistent, the patch introduces the
VERSION_SINGLE_LINE macro and changes all commands to use it instead
of open coding the version string.
That's because recv_init() is called before the command line arguments
are parsed, so the loglevel has not been set at this point. Other
programs have similar problems.
Fix these problems by always setting the loglevel right after a parser
has been called so that the init functions run *after* loglevel has
been set.

Don't check return value of command line parsers unnecessarily.
All gengetopt parsers except the one for para_client are generated
without the --no-handle-error option, i.e. these parsers exit on errors.
Hence it is pointless to check return values.

Simplify i9e_line_handler.
The line handlers of all three users of the i9e API (play, client
and audioc) return immediately if the passed line is NULL or the
empty string. Hence we may call the line handler only if there is a
non-empty line to dispatch.
Moving the check for a non-empty line to generic i9e code simplifies
the three line handlers a bit and avoids code duplication.

Fix compilation on Ubuntu precise.
This distro ships glibc-2.15 where clock_gettime() is part of the

alsa writer: Do not print uninitialized data.
ALSA's snd_output_buffer_string() returns the current size of valid

Currently alsa_init() ignores this fact and prints the buffer up to
the first NULL byte. Therefore it may print garbage that follows the
valid data in the buffer. If there is no zero byte after the data,
it may even segfault.
Fix this bug by using memchr() instead of strchr() and carefully
tracking the number of bytes processed.
