page read/write fixes (put into 5.5.0-rcX ?)

supposed fix on the client side ([XrdCl] PgRead: don't exceed max iovcnt. · xrootd/xrootd@8319e53 )

test gateway on 5.5.0-rc1 appears to have a ‘different’ set of issues; to be investigated.

Latest comment:
Interesting situation indeed.
the HTTP plugin does not know "a posteriori" that the request had just the permission to create but not to overwrite. I think that the only way to have a 403 is for the xrootd bridge to return kXR_NotAuthorized instead than kXR_ItExists for this case.

The alternative to make 409 a legal return code (which would make sense to me) could be discussed anyway.

async directive
