Add ability to use system libedit and update bundled libedit.
The version of libedit that is bundled with asterisk is old and has some bugs. This patch updates the bundled version of libedit within asterisk, and also updates asterisk to use the system libedit instead if one is available (and pkg-config is available). This review integrates several patches from other users specifically kkm and tzafrir.

.Nm
|

.Sh DESCRIPTION
|
||||
The

.Pp
|
||||
The format of each line is:
|

for more information.
|

.Pp
|

.Ar prog

.Ar command
|
||||
will be executed for any program that matches the regular expression.
|
||||
.Pp
|
||||
If
|
||||
.Ar prog
|
||||
is absent,
|
||||
.Ar command
|
||||
is executed for all programs.
|
||||
.Sh BUILTIN COMMANDS
|
||||
The
|
||||
.Nm editline
|
||||
library has some builtin commands, which affect the way
|
||||
that the line editing and history functions operate.
|
||||
These are based on similar named builtins present in the
|
||||
.Xr tcsh 1
|
||||
shell.
|
||||

|
||||

|
||||
