5216580d7a Don't track the contents of the execution info window
The curses library keeps track of the contents of each window, and can
redraw the screen as needed.  This means that in most cases is no need
for the TUI windows to also keep track of their contents.  This patch
removes content tracking from the execution window, leaving that to
curses.

93858ad34e Remove tui_clear_exec_info_content
After the previous patch, all calls to tui_clear_exec_info_content
come just after a call to tui_clear_source_content.  Because these two
windows are linked, I think it makes sense to have
tui_clear_source_content simply do the work.  So, this patch removes
tui_clear_exec_info_content.

e321e7ce75 Remove tui_erase_exec_info_content
One call to tui_erase_exec_info_content can be removed.  This call is
not needed because the function in question then immediately sets the
execution info window contents.

Once this is done, tui_clear_exec_info_content is just a wrapper for
the only call to tui_erase_exec_info_content, so
tui_erase_exec_info_content can be renamed and the wrapper function
removed.

cc0c3ffbc9 Two simplifications in tui-layout.c
This patch simplifies some code in tui-layout.c.

In show_layout, all the layout settings can be handled by a single
switch statement.  In show_source_disasm_command and
show_source_or_disasm_and_command, there is no need to check the
current layout, as the caller has already done so.

590042fc45 Make first and last lines of 'command help documentation' consistent.
With this patch, the help docs now respect 2 invariants:
  * The first line of a command help is terminated by a '.' character.
  * The last character of a command help is not a newline character.

Note that the changes for the last invariant were done by Tom, as part of :
 [PATCH] Remove trailing newlines from help text
 https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html
but some occurrences have been re-introduced since then.

Some help docs had to be rephrased/restructured to respect the above
invariants.

Before this patch, print_doc_line was printing the first line
of a command help documentation, but stopping at the first '.'
or ',' character.

This was giving inconsistent results :
  * The first line of command helps was sometimes '.' terminated,
    sometimes not.
  * The first line of command helps was not always designed to be
    readable/understandable/unambiguous when stopping at the first
    '.' or ',' character.

This e.g. created the following inconsistencies/problems:
< catch exception -- Catch Ada exceptions
< catch handlers -- Catch Ada exceptions
< catch syscall -- Catch system calls by their names
< down-silently -- Same as the `down' command
while the new help is:
> catch exception -- Catch Ada exceptions, when raised.
> catch handlers -- Catch Ada exceptions, when handled.
> catch syscall -- Catch system calls by their names, groups and/or numbers.
> down-silently -- Same as the `down' command, but does not print anything.

Also, the command help doc should not be terminated by a newline
character, but this was not respected by all commands.
The cli-option -OPT framework re-introduced some occurences.
So, the -OPT build help framework was changed to not output newlines at the
end of %OPTIONS% replacement.

This patch changes the help documentations to ensure the 2 invariants
given above.

It implied to slightly rephrase or restructure some help docs.

Based on the above invariants, print_doc_line (called by
'apropos' and 'help' commands to print the first line of a command
help) now outputs the full first line of a command help.

This all results in a lot of small changes in the produced help docs.
There are less code changes than changes in the help docs, as a lot
of docs are produced by some code (e.g. the remote packet usage settings).

cb44333d99 Add file offsets to the source cache
Currently, gdb stores the number of lines and an array of file offsets
for the start of each line in struct symtab.  This patch moves this
information to the source cache.  This has two benefits.

First, it allows gdb to read a source file less frequently.
Currently, a source file may be read multiple times: once when
computing the file offsets, once when highlighting, and then pieces
may be read again while printing source lines.  With this change, the
file is read once for its source text and file offsets; and then
perhaps read again if it is evicted from the cache.

Second, if multiple symtabs cover the same source file, then this will
share the file offsets between them.  I'm not sure whether this
happens in practice.

18ab23af8b Rearrange TUI data window code
An earlier patch caused tui-windata.h to be essentially empty.  And,
other earlier patches implemented TUI data window methods in any spot
that happened to be convenient at the time.

This patch rearranges all the data window code to be somewhat more
organized.  It moves tui_data_window to tui-regs.h, and moves the
implementation of all methods to tui-regs.c.  It then removes
tui-windata.h and tui-windata.c.

It also removes the "structuring" comments from tui-regs.c; these are
not the usual gdb style, and were out of date anyhow.  Finally, it
moves _initialize_tui_regs to the end of the file, per the usual gdb
convention.

88b7e7ccb9 Fix flushing bug in tui_puts_internal
A while back I changed gdb not to flush in some places.  It turned out
that this broke the TUI a little.  An easy way to see it is to run
"gdb -tui -nx", then "file gdb" at the gdb prompt.  gdb will print the
usual "Reading symbols..." message -- but it won't appear on-screen
until the reading is complete.

This patch changes the TUI to do the equivalent of line buffering in

098f9ed48e Always create an execution info window for a source window
A source or disassembly window will always have an "execution info"
window (the window along the side that displays breakpoint info), but
this isn't immediately clear from the source.  As a result, some code
has checks to see whether the execution_info is NULL.

This changes the source window base class to always instantiate an
execution_info window, then updates the rest of the code.  It also
simplifies window creation in tui-layout.c.

tui_set_layout sets regs_populate using:

      regs_populate = (new_layout == SRC_DATA_COMMAND

Then later it checks this variable:
