set_my_locale function gets charset from locale if no language variable
found in user's prefs. Fixes possible problem when $default_charset and
$squirrelmail_default_language are incorrectly set in config.
sqgetGlobalVar($name, $value [, location] );
This function looks for a variable named $name.
If found, it sets the value into $value (in signature, is &$value) and
returns true. If the variable is not found, the function returns false.
The optional constant allows you to pick which location to
check for the variable in. If none is specified, it will check,
in this order, $_SESSION, $_POST, $_GET. These are defined constants
for use with this function:
SQ_INORDER - same as specifying nothing, check all three.
SQ_SESSION
SQ_POST
SQ_GET
It is recommended that plugins, all functions use this instead of
directly accessing $_SESSION/$_POST/$_GET arrays, as we have
already taken care of scope (global, etc).
The Administration plugin has been updated to use this function,
as an example.
This is an alternative to sqextractGlobalVar($name), which looks
for a var named $name in the SESSION/GET/POST arrays, and creates
a global variable if defined.
we split the streams to the new RC for 1.4.
check_sm_version performs similar function to check_php_version, and
will return true if version is >= what is specified.
For Thijs/Jonathan - the check_sm_version will return false if the
constant it checks against is not defined, making the function itself
safe for previous levels, should you want to roll it back to stable
to allow plugin developers to use the check_sm_version function to
test for 'new' elements like SM_PATH, etc. that are present in 1.3.x
and up.
More info (though not a ton, I'll admit) is in the sm2-planning module

between a 0 value, and an unset value using ===.
Certain prefs were unsaveable after the XSS changes, which
cast zero values to ints (instead of strings), causing
them to pass the $set_to == '' check, and thus be treated
as an unset value, rather than a value of 0.

fix for displaying the hide unsafe images link. If you show the unsafe
images, has_unsafe_images = false because it looks for the image
replacements. The hide unsafe images link was never initialized correct.
