Typo in man page

bug #56027

fix UTF-8 characters with more than 2 bytes

Characters are stored as uint32 nowadays. Looking at the lower bytes
only seems to be an oversight from the fontx clean up.

Fixes: f18f5d0da1d4 get rid of fontx

drop unnecessary BEL from bracketed paste mode sequence

there is no BEL in enable/disable bracketed paste mode sequence, so we
shouldn't unnecessarily print it

Fix extra characters when sending a command in one go

This closes bug #52372: Giberish printed to screen window in certain
situations.

When sending "^An", most of the time, screen first receives "^A", then
it receives the "n". This means that in the ProcessInput2 function,
ilen == 1 after the escape character has been seen, ilen is decremented
and the ProcessInput2 function returns.

When "^An" is sent in one go, for example when pasting or when using a
special shortcut, ilen is not 1 when the escape character is seen. In
this case, the s variable was incremented, but ilen was not decremented.
This leads the function to read an extra character which does not
exists.

This regression was introduced in 2fab4d6f73, as reported in the bug
report.

This can be tested by having a command in the selection:

echo -ne '\x01n' | xclip -i

And pasting it (in this case, you might see the closing bracketed paste
sequence, but that is another problem).

make build date reproducible

Based on https://reproducible-builds.org/docs/source-date-epoch/
They suggest "BUILD_DATE ?=", but it seems to be evaluated for each file
separately, so us "BUILD_DATE :=" to set it once.

Fix blanker to work when screen is suid root

* Change RunBlanker to call OpenDevice so permissions on slave
  PTY are correctly set.
* Update handling of file descriptors after fork to be similar to
  ForkWindow on at pty (fixes debug and leaked descriptors)
* Allow display of error message when display blocked by blanker
  (because message is probably from blanker failing to start)

Prevent Panic causing Panic, and children removing sockets

* Set eff_uid/eff_gid after setuid/setgid to prevent nested Panic
  MakeClientSocket calls xseteuid(eff_uid=0) - results in nested
  Panic and SendErrorMsg not getting sent.
* Set ServerSocket to -1 after fork so that child Panic doesn't
  remove socket in eexit.
