d343e8203d conf: Remove ATTRIBUTE_NONNULL for virDomainQemuMonitorEventNew
Commit 17561eb36 modified the logic to check "if (!event)" for an
attribute that was not supposed to be passed as NULL.  This causes
the static checker/Coverity build to fail. Since the check is made,
alter the header.

Also add an error message since returning -1 without some sort of
error message as previously would have happened with the failed
VIR_STRDUP so that the eventual error doesn't get the default
for some reason message.

5fdad0db2c util: buffer: Properly URLencode strings
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.
