[gdb/doc]: Updated manpages to be consistent with help

Browse Source 
Updated manpages to be consistent with help information provided by the
binary. The main changes are:

* Making all long-form options have '--', instead of a single '-';
* added most of the missing options to the manpage;
* removed the information about using '+' instead of '-', since it
  doesn't seem to be supported anymore.

This also fixes 2 upstream bugs:
* https://sourceware.org/bugzilla/show_bug.cgi?id=23965; by adding
--args to the manpage
* https://sourceware.org/bugzilla/show_bug.cgi?id=10619; by adding the
double dashes

Any arguments other than options specify an executable
file and core file (or process ID); that is, the first argument
encountered with no
associated option flag is equivalent to a @option{-se} option, and the second,
associated option flag is equivalent to a @option{--se} option, and the second,
if any, is equivalent to a @option{-c} option if it's the name of a file.
Many options have
both long and short forms; both are shown here. The long forms are also

more usual convention.)

in sequential order. The order makes a difference when the @option{-x}
option is used.

@item -cd=@var{directory}
@item --batch-silent
Run in batch mode, just like @option{--batch}, but totally silent. All @value{GDBN}
output is supressed (stderr is unaffected). This is much quieter than
@option{--silent} and would be useless for an interactive session.
This is particularly useful when using targets that give @samp{Loading section}
messages, for example.
Note that targets that give their output via @value{GDBN}, as opposed to writing
directly to @code{stdout}, will also be made silent.
@item --args @var{prog} [@var{arglist}]
Change interpretation of command line so that arguments following this
option are passed as arguments to the inferior. As an example, take
the following command:
@smallexample
gdb ./a.out -q
@end smallexample

It would start @value{GDBN} with @option{-q}, not printing the introductory message. On
the other hand, using:
@smallexample
gdb --args ./a.out -q
@end smallexample
@noindent
starts @value{GDBN} with the introductory message, and passes the option to the inferior.
@item --pid=@var{pid}
Attach @value{GDBN} to an already running program, with the PID @var{pid}.
@item --tui
Open the terminal user interface.
@item --readnow
Read all symbols from the given symfile on the first access.
@item --readnever
Do not read symbol files.
@item --dbx
Run in DBX compatibility mode.
@item --return-child-result
@value{GDBN}'s exit code will be the same as the child's exit code.
@item --configuration
Print details about GDB configuration and then exit.
@item --version
Print version information and then exit.
@item --cd=@var{directory}
Run @value{GDBN} using @var{directory} as its working directory,
instead of the current directory.
@item -fullname
@item --data-directory=@var{directory}
@item -D
Run @value{GDBN} using @var{directory} as its data directory. The data
