BUG/MINOR: http: fix encoding of samples used in http headers
The binary samples are sometimes copied as is into http headers.
A sample can contain bytes unallowed by the http rfc concerning
header content, for example if it was extracted from binary data.
The resulting http request can thus be invalid.
This issue does not yet happen because haproxy currently (mistakenly)
hex-encodes binary data, so it is not really possible to retrieve
invalid HTTP chars.
The solution consists in hex-encoding all non-printable chars prefixed
by a '%' sign.
No backport is needed since existing code is not affected yet.
