Backport !1173 “gvariant: Limit recursion in g_variant_parse()” to glib-2-62
The token parsing done by g_variant_parse() uses recursive function
calls, so at some point it will hit the stack limit. As with previous
changes to GVariantType parsing (commit 7c4e6e9f), limit the level
of nesting of containers parsed by g_variant_parse() to something
reasonable. We guarantee 64 levels of nesting, which should be enough
for anyone, and is the same as what we guarantee for types.
(Backport to 2.62: Dropped the new G_VARIANT_PARSE_ERROR_RECURSION
error code in favour of G_VARIANT_PARSE_ERROR_FAILED, to avoid adding
API.)
