When running gdb.base/compare-sections.exp with target board -fPIE/-pie, we
get:
...
FAIL: gdb.base/compare-sections.exp: after run to main: compare-sections -r
...
The test expects the read-only sections to have the same contents as in the
file:
...
# Assume startup code doesn't change read-only sections.
compare_sections "-r"
...
but that's not the case for PIE executables.
Fix this by allowing mismatched read-only sections for PIE executables.
Tested on x86_64-linux.

x86-64: Restore PIC check for PCREL reloc against protected symbol
moved PIC check for PC-relative relocations to elf_x86_64_check_relocs.
Since linker defined symbols may not be processed at the time, we need
to move the check back to elf_x86_64_relocate_section.

The TUI execution info window is unusual in that it is always linked
to a source or disassembly window. Even updates of its content are
handled by the source window, so it really has no life of its own.
This patch removes this window entirely and puts its functionality
directly into the source window. This simplifies the code somewhat.
This is a user-visible change, because now the box around the source
(or disassembly) window encloses the execution info as well. I
consider this an improvement as well, though.
Note that this patch caused ncurses to start emitting the "CSI Z"
sequence, so I've added this to the test suite terminal
implementation.

A few TUI functions take a "noerror" parameter. This is only checked

When running gdb.base/compare-sections.exp with -fPIE/-pie, we get:

(gdb) FAIL: gdb.base/compare-sections.exp: read-only: get value of read-only section

The problem is that that "maint info sections" prints an unrelocated address:
...
[0] 0x00000238->0x00000254 at 0x00000238: .interp ALLOC LOAD READONLY \
DATA HAS_CONTENTS
...
while the test expects a relocated address.
Given that the documentation states that the command displays "the section
information displayed by info files", and that info files shows relocated
addresses:
...
0x0000555555554238 - 0x0000555555554254 is .interp
...
fix this by showing relocated addresses for maint info sections as
well.

The TUI currently has two different ways to resize a window: the
resize method, and the methods make_invisible_and_set_new_height and
make_visible_with_new_height.
There's no deep reason to have two different ways to resize a window,
so this patch unifies them, leaving just the "resize" method.
This also changes the locator to be handled more like an ordinary
window and less like an adjunct of the associated source window.

This fixes a problem originally reported at
https://github.com/riscv/riscv-binutils-gdb/issues/173
If you have code linked at address zero, you can have a lui instruction
loading a value 0x800 which gets relaxed to a c.lui which is valid (c.lui 0x1
followed by addi -0x800). Relaxation can reduce the value below 0x800 at which
point the c.lui 0x0 is no longer valid. We can fix this by converting the
c.lui to a c.li which can load 0.

When resizing a window, the TUI currently first makes it invisible,
then changes the size, and then restores its visibility.
I think this is done because curses doesn't truly support resizing a
window -- there is a "wresize" extension, but the man page says it
isn't available in all versions of curses.
First, this is probably not a major problem any more. I imagine most
of those old systems are gone now.
Second, I think it's a better API to have this detail hidden inside of
the resize method.
This patch changes the code to follow this idea, and changes the
ordinary resize method to use wresize when it is available. The
special case for the command window is also moved to methods on the
command window.

Currently the TUI does separate bookkeeping to track which source

There is no longer any need for tui_alloc_source_buffer. The two
callers of this function immediately change the contents of the
window, undoing the work done by this function.
This required adding a move constructor to tui_source_element -- a
mildly surprising find, but without this, resizing the vector will
cause crashes. This issue was masked earlier because
tui_alloc_source_buffer handled this.
Note that a patch for this bug was submitted here:

tui_make_status_line uses string_file where a simple std::string
constructor would do. This makes this change.

* tui/tui-stack.c (tui_make_status_line): Use string constructor.
The locator is mostly implemented in tui-stack.c. This moves the
remaining bits to tui-stack.c and tui-stack.h, as appropriate.

An earlier patch added a couple of FIXME comments to tui-layout.c.
This removes them. This is possible due to the previous patch that
changed how boxing works in the TUI -- now, no special case for the
command window is needed in box_win.

* tui/tui-layout.c (show_source_disasm_command)
(show_source_or_disasm_and_command): Use make_visible method, not
tui_make_window.
* tui/tui-command.h (struct tui_cmd_window) <make_visible>:
Remove.
In the TUI, whether or not a window can be boxed is a property of the
window's type. This adds a can_box method to the window classes, and
changes tui_make_window to defer to this, removing the "box_it"
paramter. This also lets us remove "enum tui_box", as it is no longer
used.

This test has many hardwired assumptions that pathnames on build and
host are the same, and that POSIX pathname syntax is used. This
results in dozens of failures on a remote Windows host. Fixing these
assumptions would involve nontrivial rewrites; meanwhile, let's make
the test results reflect the reality that this testcase isn't supported
on remote host.

* gdb.dwarf2/dw2-dir-file-name.exp: Skip on remote or
Windows host.
This group of tests assume that the gdb "shell" command launches a
POSIX-compliant shell supporting the PPID environment variable, which
is used to get gdb's pid for killing it from a remote_exec shell. But
on Windows host "shell" launches cmd.exe, which doesn't have an
equivalent query.

Pedro pointed out that target_write_memory should use gdb::byte_vector
rather than std::vector<unsigned char>.

Dejagnu produces an objdir like /c/, but GDB expects something like c:/.
So fix it up in lib/gdb.exp.

gdbserver's write_inferior_memory uses a static variable to avoid
memory leaks, and has a comment referring to the lack of cleanups.
This patch removes this comment and the code in favor of a
straightforward use of std::vector.

* target.c (write_inferior_memory): Use std::vector.
A customer program had a DWARF CU that consisted of just a CU DIE,
without any children. In this situation, scan_unit_for_symbols will
try to read past the end of the current CU, and will take use the
first bytes of the next CU as an abbrev, printing an error message.
This patch fixes the bug by changing scan_unit_for_symbols to stop at
the end of the CU rather than the end of the .debug_info section.

* dwarf2.c (scan_unit_for_symbols): Check for end of CU, not end
of section.
