626aac16bc splice() per direction, pipes per connection, automatic mode 
-s takes the directions to splice: -s1 what the server sends (downloads),
-s2 what the client sends (uploads), -s3 both. -s alone (-s7) splices both
only where it pays, as -s5 and -s6 do for one direction:
- a body of known length is spliced if at least 16K of it is left to read
  once what is already buffered is counted, so an answer read whole with
  its headers is just copied;
- a stream of unknown length starts copied, is spliced after 2 reads in a
  row of at least 16K, and goes back to copying after 3 splices in a row
  of less than 4K, once its pipe is empty.

Pipes are made when a direction first splices and kept with the
connection for its next mappings, so a kept-alive connection no longer
makes and closes two pipes per request; one left holding data by an
error or a timeout is closed. The direction not spliced keeps its buffer.

Before, -s spliced both directions and every mapping made both pipes,
which made small answers slower than without splice: with kept-alive
50K answers 2 pipe2() and 4 close() per request, now none.

Also corrects the default buffer size in the -b help (65536 for TCP).

f2ae920db2 Build the mail proxies and FTP only when they are asked for 
pop3p, imapp and smtpp are built with MAILPROXY=true, and ftppr and the
ftp:// scheme of the HTTP proxy with FTP=true; with CMake the switches are
3PROXY_USE_MAILPROXY and 3PROXY_USE_FTP. Neither is in a default build, and
the standalone binaries follow what was built.

A configuration naming one of them is still read either way. The three mail
protocols amount to a STARTTLS negotiation now that mail is carried over
TLS, so without a proxy of their own those names are tlspr speaking the
protocol: the file holds a stand-in which sets the protocol for the
connection and returns tlspr for the caller to run, which serves the
service name and a parent chain alike and leaves conf.c and the redirect
table untouched. FTP has no such fallback, so the service is known, answers
nothing and logs the refusal.

The Linux workflow builds both, so all of it is still compiled and run.

4f0f3c81e1 add 'cacheacl' auth type, dstaddr, dstport, dsthost, dstoper, srvaddr and srvport authcache types; allow to configure authcache by service 
'auth cacheacl ...' is identical to 'auth cache ...' except ACL is not checked for cached authentication. dstaddr, dstport, dsthost and dstoper (operation) are intended to be used with cacheacl. For example

authcache user,ip,password,dstaddr 600
auth cacheacl iponly strong

allows user to access destination ip without ACL/password revalidation if he has cached attempt to the same ip from the same ip with the same username and password.

srvaddr, srvport are useful to only match with cached attempts to the same `internal` address / service port.
