GString is surprisingly similar to what libvirt was doing painstakingly

rfc3986 uses uppercase characters so switch to using them as well.
Signed-off-by: NPeter Krempa <pkrempa@redhat.com>

According to rfc3986:

2.3.  Unreserved Characters

   Characters that are allowed in a URI but do not have a reserved
   purpose are called unreserved.  These include uppercase and lowercase
   letters, decimal digits, hyphen, period, underscore, and tilde.

      unreserved  = ALPHA / DIGIT / "-" / "." / "_" / "~"

   URIs that differ in the replacement of an unreserved character with
   its corresponding percent-encoded US-ASCII octet are equivalent: they
   identify the same resource.  However, URI comparison implementations
   do not always perform normalization prior to comparison (see Section
   6).  For consistency, percent-encoded octets in the ranges of ALPHA
   (%41-%5A and %61-%7A), DIGIT (%30-%39), hyphen (%2D), period (%2E),
   underscore (%5F), or tilde (%7E) should not be created by URI
   producers and, when found in a URI, should be decoded to their
   corresponding unreserved characters by URI normalizers.

Thus we must not include few other characters which don't match
c_isalpha to conform to the rules.

After the conversion of all callers that would pass true as @dynamic to
a different function we can remove the unused argument now.

Additionally modify the return type to 'size_t' as indentation can't be
negative and remove checks whether @buf is passed as it's caller's duty
to do so.

Rather than setting usage error truncate the indentation level. Having

After conversion to g_strdup, the helpers now always return success.
Remove the return value to simplify the callers.

Note that many occurrences of these is in the code generated by
gendispatch.pl. Since gendispatch aggregates many cases together an
incremental conversion would require more invasive changes to
gendispatch for the time of conversion which doesn't make sense.

Also in many cases the helper was the last place where the 'error:'
label was used and thus also those conversions must be included in this
patch.
