Release 1.2.2

[rockowitz]

Release 1.2.2 is now available as branch 1.2.2.

Significant changes since release 1.2.1:

This release improves the handling of and messages regarding DDC communication failures with errno EBUSY. In particular, this error occurs when driver ddcci is loaded.

• Command detect: If DDC communication fails with error EBUSY, report the display as "Busy" instead of "Invalid" and suggest use of option --force-slave-address.
• Command environment: If driver ddcci is loaded, suggest use of option --force-slave-address.
• Messages regarding EBUSY errors are always written to the system log.
• Added API functions ddca_enable_force_slave_address(), ddca_is_force_slave_address_enabled().

Miscellaneous changes:

• When building ddcutil, allow for linking a static library if configure option --enable-static is set. By default, static libraries are not built.
• Calls to function __assert_fail() have been replaced with exit() in traced assertions. __assert_fail is part of the Linux implementation of assert(), but is not in the C specification. This changes simplifies porting of ddcutil to environments lacking this function.
• Avoid compilation warnings when assertions are disabled (NDEBUG is defined).
• Only write messages regarding ddcutil starting and termination if option --syslog is specified.
