Refactor much of the new code in log.c
Add new functions: cf_load_strict() and cf_reload_strict() for use by the
server, which does not want to overwrite its in-memory config at all if there
is any defect in the config file. However, commands always want to overwrite
the default in-memory config, even with a defective config file, so that
logging has a chance to succeed.
Added `log_format.dump_config` boolean config option
Indepent configuration of show_pid, show_time and log level for each
destination
Update test scripts for new config options
Include xprintf.c in MDP client source files (now used by log.c)
Upgrade configuration schema macros to allow optional "default label"
argument to SUB_STRUCT and VALUE_SUB_STRUCT elements.
New STRUCT_DEFAULT section declares alternative STRUCT default values
with a label.
Sometimes, when adding a PIN to a keyring (eg, when opening a keyring
file), a SEGV would be caused while trying to validate the MAC for an
entry which apparently had zero keypair entries.
Changed some keyring struct 'int' fields to 'unsigned int', to ensure
that comparison logic behaves as expected.
Refactored some keyring code for more clarity and code maintenance
safety.
Added TODO comment about keyring file format non-back-compatibility.
The 'includeTests' function failed if /bin/bash was not available or not
the same as the Bash used to run the top test script. This failed on
Solaris, where /usr/bin/bash is too old, and a privately-built Bash must
be used to run the test scripts.
Remove array key SORTED flag; all arrays are now sorted by key
Use representation's comparison function for sorting arrays, not
a schema-supplied comparison function.
All STRUCT cf_fmt_config_xxx() functions omit invalid values, silently
if the invalid value is the default, otherwise with a non-CFOK return
value.
The "config dump --full" option includes all options with valid values,
otherwise omits options having default values.
