Change a test case: configuration options are now case sensitive.
Fix config file load and parse logic in conf.c, always copy 'debug' flags
from config.debug.
The config schema 'interfaces' option is no longer MANDATORY.
Introduce new CLIFLAG_PERMISSIVE_CONFIG to supress bad-config ERROR messages
from the 'config set' and 'config get' commands.
Refactor cli_execute() into cli_parse() and cli_invoke(). Use *const* struct
command_line_option everywhere.
The new header "os.h" defines a supplemental API around existing basic
operating system services (system calls and standard library functions).
Moved some function prototypes from serval.h and net.h into os.h.
This allows non-servald executables to take advantage of this API without
having to include serval.h and bringing in all the other servald link-time
baggage.
Config Object Model parser now returns bitmask result of CFxxx flags and only
allocates root node if the config file is non-empty.
Added emalloc_zero().
Rework ARRAYs, replacing label string with typed key, declaring KEY and VALUE
independently.
Implement dna.helper.argv array using key of type unsigned short.
Implement mdp.iftype.<interfacetype>.tick_ms using key of type short for the
interface type code.
The dna.helper.argv validation function now sorts the array in numerical order
of labels using qsort(3).
Add LABELLEN argument to ARRAY schema macros, to control the size of the
label[] string (was fixed at 41 chars before).
Add optional validator functions for STRUCT and ARRAY parsing. Tighten up
logic for parsing STRUCTs and ARRAYs and the result flags. Improve
documentation in block comments. Add CFUNSUPPORTED result flag.
Refactor ARRAY_xxx() schema declaration macros to fix problem in ARRAY_STRING().
Add dna.helper.executable, dna.helper.argv and server.chdir to config schema.
Replace ARRAY() macro with ARRAY_ATOM(), ARRAY_STRING(), ARRAY_NODE() and
ARRAY_STRUCT().
Change parse function return value to flag bits, add CFEMPTY, rename CFMISSING
to CFINCOMPLETE, improve logic around mandatory struct items.
Renamed struct config_node to struct cf_om_node.
Refactor to make opt_parsing() functions simpler for ATOM -- no need to check
for missing text or unsupported child nodes, or log parse failures.
Introduce NODE option which passes whole config_node struct to parsing
function.
Add str.h to list of Serval header files. Make the NaCl objects not dependent
on Serval header files, so that the entire NaCl source does not get re-built
when editing serval.h or str.h etc.
Move alloca_tohex() from serval.h into str.h so it can be used stand-alone.
Rename str_to_ll_scaled() to str_to_int64_scaled(). Add str_to_uint64_scaled()
and scale_factor().
Add a few more URI parsing functions. Move some functions out of str.c and
into str.h as inline functions.
Add strn_startswith() and strncase_startswith().
Make all str*_startswith() functions take const char * arguments, to make it
possible to do safe programming with consts.
