Fix a pair of screen-resizing issues in TUI
This patch fixes a pair of TUI issues related to screen resizing:
1. In tui_handle_resize_during_io(), when the TUI screen gets resized,
we fail to update GDB's idea about the height of the output window.
You can see this bug by doing:
a. Enter TUI mode.
b. "show height"
c. Resize the terminal.
d. "show height"
And observe that despite resizing the terminal, the reported height
remains unchanged. Note that a similar issue exists in the CLI.
The fix for this is simple: call tui_update_gdb_sizes() after performing
a resize, so that the "height" variable remains consistent with the
height of TUI's output window.
2. In tui_enable(), the call to tui_update_gdb_sizes() may clobber
readline's idea of the actual screen dimensions, and a subsequent
pending resize will use bogus terminal dimensions.
You can see this bug by doing:
a. Enter TUI mode.
b. Exit TUI mode.
c. Resize the terminal.
d. Enter TUI mode.
e. Press a key to resize the screen.
And observe that the terminal gets incorrectly resized to the wrong
dimensions. To fix this issue, we should oppurtunistically resize the
screen in tui_enable(). That way we eliminate the possibility of a
pending resize triggering right after we call tui_update_gdb_sizes().
gdb/ChangeLog:
* tui/tui-io.c (tui_handle_resize_during_io): Call
tui_update_gdb_sizes() after resizing the screen.
* tui/tui.c (tui_enable): Resize the terminal before
calling tui_update_gdb_sizes().
