We already had uuid_answer and uuid_pre_answer, so we might as well
add uuid_ring_ready.

Since libedit originates from NetBSD, this and other BSDs use the
official version while Linux distributions tend to use the
autotoolized fork. The official version does not install a .pc file so
we cannot rely exclusively on pkg-config for detection.

Don't use CFLAGS or CXXFLAGS for this because AC_CHECK_HEADER only
uses CPPFLAGS.

FS-6413 --resolve with this patch you will need to make sure the boxes have the clocks synced and both started inside the same occurence of the most recent new year.

also push PKG_CONFIG_SYSROOT_DIR and set some test results that can not be figured out during cross compile explicitly for arm-linux-gnueabi*|arm-*-linux-gnueabi*

push sysroot down to other libs and things that don't use libtool as well, so you don't need to specify it in a bunch of different ways when using it.

Previously we enabled libedit support opportunistically if it was
neither enabled nor disabled explicitly.  But this can result in
people being confused by libedit features not being available when
they really just need to install dependencies.  With this change,
we'll break on configure if libedit-dev isn't there.  If the user
really wants to build without libedit they just need to explicitly
disable it.

Now that all output should end in a newline, we don't need to play
tricks with getting certain escape codes out ahead of buffered output.

This updates what we tried to do in commit
991b83d2.

This partially reverts commit
80561250.

The issue is that sofia siptrace output doesn't end each line with a
newline.  Instead it sends a separate newline afterward, which comes
in as a separate event body.  With the new EL_REFRESH code in effect
the line is being cleared after the siptrace output has been written
but before that next newline comes in.

With our own refresh code this doesn't happen because of slight
differences in where the stdio buffers get flushed compared to where
the output of clear_line() ends up.

This is a bit of a clumsy workaround.  But we'll fix it first, then
refactor.

We turn ON the features with a newer libedit.

This fixes commit 4f54f912.

Using the system libedit means that libedit will again make absolute
movements on certain kinds of terminals.  Older versions of libedit
without EL_PROMPT_ESC miscalculate the length of the prompt.
Combined, this results in the cursor ending up in the wrong place.

We knew this was a possibility when we moved to system libedit, and
we're OK with it.  We certainly lived without this fancy prompt
feature for a long time.

This change puts back in place detection of the terminal type when
EL_PROMPT_ESC isn't available.  On these older versions of libedit,
we'll only enable the fancy features when we know that libedit will
only make relative movements and not tickle the bug.

This partially reverts commit:
b9b77bd6

Newer versions of libedit provide an EL_REFRESH mechanism for
redrawing the prompt.  We had previously written our own code to
handle this.  In theory handing this over to libedit should be better.

Unfortunately when using EL_REFRESH the output of sofia siptrace isn't
showing up.  We're working on that, but for now we're just force own
our redrawing code to be used instead.
