In ap_resolve_env(), the string returned from getenv() should be copied since
the returned string may be statically allocated.

This fixes an issue where the value for the last env var is substituted for all
env vars in a directive containing multiple env vars.

I have choosen "unlikely" because this bug has been around for ever ([1]) and the pool is only "cleared"; that is to say, the data is still valid, but the memory *could* be re-used.

                 onsuccess vs always

In PR 62380 a user was confused why Header set always
was not overriding a header set by a HTTP backend managed
via mod_proxy_http. The difference between 'onsuccess'
and 'always' is really subtle, even if somebody is familiar
with r->headers_out and r->err_headers_out and the httpd's
internals.

As Stefan mentioned over email, the absence of a "normalized"
headers list in the response should be explained, so I tried to
do so in this commit.

  The certificates and keys loaded during configuration time got lost during
  runtime if e.g. SSLProxyMachineCertificate{File|Path} was set on virtual host
  level and there was an SSL directive at directory level, e.g. SSLRequire.
  This fixes a regression likely introduced in r1740928.
