LogC version 0.5.0

Fixed
* cross compilation configure error
* error when inline function is exported

Changed
* build system changed from Autotools to Meson

LogC version 0.4.0

Added
* `liblogc_config` for configuration parsing using libconfig
* log function with critical level `log_fatal` and `fatal` macro that
  calls `exit()` to terminate execution of application.
* log_argp argument `--no-syslog` for daemon logs as there would be no
  way to disable default syslog otherwise.

Changed
* Syslog configuration is now no longer configured using boolean in the
  log structure but rather by using functions with default handled the
  same way as for standard error fallback output.

Removed
* log_argp argument `--no-stderr` as it is easy to redirect or drop
  standard error output without needing this option

LogC version 0.3.0

Added
* support for binding logs to allow combination of multiple log
  instances to single one
* signal masking for `_logc` function and thus for all log outputing
  functions

Changed
* Some functions return defaults directly without allocating internal
  log structure

Fixed
* detection of distribution archive for gperf detection when building
  outside of source files tree
* custom syslog format memory leak

LogC version 0.2.1

Fixed
* version specification in pkg-config files
* distribute archives
* code coverage generation library inclusion

Changed
* Missing `cppcheck` is not fatal error if linters are enabled

LogC version 0.2.0

Added
* Details about compilation and testing to README.adoc
* Output format fragment `LOG_FP_LEVEL_NAME`
* Output format field `%|` that is handled as "else" inside conditions
* Support for output level offset
* Function `log_offset_level` to set level relative to current setting
* Support for output to syslog
* New log creation helper macro `DAEMON_LOG` for applications commonly
  started in background
* `--log-file` argp option
* `--log-level` argp otion

Changed
* Log macros for specific log prefixed with `log_`
* Log macros using `DEFLOG` renamed from upper-case to lower-case
* Macro `log` was renamed to `logc` to not collide with `math.h`'s `log`
* Function `_log` was renamed to `_logc` to be consistent with `log`
  rename
* Code is now compiled explicitly with C11 standard support
* Output format not-empty condition do not investigate sub-conditions,
  instead it considers them non-empty if they condition is fulfilled.
* Default formats now use `LOG_FP_LEVEL_NAME` for message type
  representation
* How message level and log level is mixed and because of that most of
  the function now take `int` instead of `enum log_level`
* Environment variable `LOG_LEVEL` is now expected to be number and not
  string
* Message level enum renamed from `log_level` to `log_message_level` and
  values are shifted partially to negative
* `ASSERT` renamed to `assert` and `assert` to `log_assert` in
  `logc_assert.h`
* Utility macro `std_fatal` now provide result from statement

Removed
* Output format fields `%l` and `%L`

Fixed
* Linter and tests inclusion when they were not enabled by configuration
  script
