Update configuration option definition array (g_config_defs) to add
value kind attribute as 4th entry in definition list. This attribute has
following possible values: 'i' for integer, 's' for string, 'b' for
boolean, 'l' for colon-separated list, 'o' for other.
Update module specification parsing mechanism to add a getavails
argument. It indicates that available modules matching spec should be
searched in enabled modulepaths to record them in module version
specification structure.
When searching for available matching modules, disable extra match
search to avoid an infinite resolution loop.
Extra specification in module search query is only allowed on search
sub-commands (avail, paths, whatis). An error is raised when parsing a
module specification if it contains an extra specification on a
non-search context.
xtspec argument is added to parseModuleSpecification procedure to know
if extra specification is allowed or not.
Update getDiffBetweenArray procedure to add notset_equals_empty argument
(disabled by default). When enabled not-set element in array is
equivalent to element set to an empty value.
Correct source-sh tests in 50/400 to succeed when tests are run in an
environment where module is defined but has been uninstalled. It
corresponds to the environment created for 'mrel' script execution.
Add an utility library that supersedes the sysconf function from libc.
The sysconf function from this added library always returns an error
(-1). It is used for coverage test of the sysconf call made within the
Envmodules_InitStateUsergroupsObjCmd function of the Tcl extension
library.
Remove entirely the work on the noglob_eval_shells option as enclosing
in quotes the generated output of modulecmd.tcl to pass it to the eval
command is equivalent to disable the pathname expansion mechanism of
sh-kind shells.
Rename the parseModuleVersionSpecifier procedure into
parseModuleSpecification, as it will now on take in charge more than
just the version specifier parsing (specified variants will be parsed
too).
