3847a7bfbf Add timestamps to "maint time" output
Currently "maint time" will print the amount of time a command took.
Sometimes, though, it's useful to have a timestamp as well -- for
example if one is correlating a gdb log with some other log.

This patch adds a timestamp to the start and end of each command when
this setting is in effect.

This also removes a "//" comment and changes scoped_command_stats to
use DISABLE_COPY_AND_ASSIGN; two minor things I noticed while working
on the patch.

Tested on x86-64 Fedora 29.

237df8fe18 [BFD, AArch64] Fix PT_GNU_PROPERTY alignment issue
If the new GNU property section was being created by the linker
(this will happen only if none of the inputs have any GNU property
section but the command line to the linker forces a bti with
--force-bti), the alignment of the section and hence the program
header of PT_GNU_PROPERTY type was not being set correctly. This
patch fixes this issue.

312617a3d0 gdb/riscv: Don't error when decoding a 6 or 8 byte instruction
If the RISC-V prologue scanner finds a 6 or 8 byte instruction we
currently throw an internal error, which is not great for the user.

A mechanism already exists in the prologue scanner to leave
instructions marked as unknown so that we can stop the prologue scan
without raising an error, this is used for all 2 and 4 byte
instructions that are not part of the small set the prologue scanner
actually understands.

This commit changes GDB so that all 6 and 8 byte instructions are
marked as unknown, rather than causing an error.

b02f78f928 Introduce and use make_unique_xstrdup
Adds an utility function to make it shorter to write the common case
of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it
throughout.

Note: I tried to put this in common/common-utils.h near skip_spaces,
etc. but that is included in common/common-defs.h before
common/gdb_unique_ptr.h is included, so it would fail to compile
because gdb::unique_xmalloc_ptr isn't defined at that point yet.  I
tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but
that doesn't work because gdb_unique_ptr.h depends on common-utils.h
for xfree.

6b22174ff1 libctf: look for BSD versus GNU qsort_r signatures
We cannot just look for any declaration of qsort_r, because some
operating systems have a qsort_r that has a different prototype
but which still has a pair of pointers in the right places (the last two
args are interchanged): so use AC_LINK_IFELSE to check for both
known variants of qsort_r(), and swap their args into a consistent order
in a suitable inline function.  (The code for this is taken almost
unchanged from gnulib.)

(Now we are not using AC_LIBOBJ any more, we can use a better name for
the qsort_r replacement as well.)

66d8c86285 Improve usability and/or readibility of help and apropos output.
The "help" command can output long list of command names or classes.
Use the title style to style the command names or classes to make
the output more readable.

Similarly, change "apropos" command to also style the command names.

It is sometimes unclear why "apropos REGEXP" lists some commands,
and then the user has to manually do 'help command' for all commands
listed by "apropos" to see more details about the matching commands.

=> Add an optional flag -v so that "apropos -v REGEXP":
  * outputs the full documentation of matching commands.
  * highlights the documentation parts matching REGEXP.

Highlight style is used by fputs_highlighted to highlight the parts of

947d39462e Implement | (pipe) command.
The pipe command allows to run a GDB command, and pipe its output
to a shell command:
  (gdb) help pipe
  Send the output of a gdb command to a shell command.
  Usage: | [COMMAND] | SHELL_COMMAND
  Usage: | -d DELIM COMMAND DELIM SHELL_COMMAND
  Usage: pipe [COMMAND] | SHELL_COMMAND
  Usage: pipe -d DELIM COMMAND DELIM SHELL_COMMAND

  Executes COMMAND and sends its output to SHELL_COMMAND.

  The -d option indicates to use the string DELIM to separate COMMAND
  from SHELL_COMMAND, in alternative to |.  This is useful in
  case COMMAND contains a | character.

  With no COMMAND, repeat the last executed command
  and send its output to SHELL_COMMAND.
  (gdb)

For example:
  (gdb) pipe print some_data_structure | grep -B3 -A3 something

The pipe character is defined as an alias for pipe command, so that
the above can be typed as:
  (gdb) | print some_data_structure | grep -B3 -A3 something

If no GDB COMMAND is given, then the previous command is relaunched,
and its output is sent to the given SHELL_COMMAND.

This also defines convenience vars $_shell_exitcode and $_shell_exitsignal
to record the exit code and exit signal of the last shell command
launched by GDB e.g. by "shell", "pipe", ...

68bb5386b8 Add previous_saved_command_line to allow a command to repeat a previous command.
Currently, a previous command can be repeated when the user types an
empty line.  This is implemented in handle_line_of_input by
returning saved_command_line in case an empty line has been input.

If we want a command to repeat the previous command, we need to save
the previous saved_command_line, as when a command runs, the saved_command_line
already contains the current command line of the command being executed.

As suggested by Tom, the previous_saved_command_line is made static.
At the same time, saved_command_line is also made static.
The support functions/variables for the repeat command logic are now all
located inside top.c.

a0486bac41 libctf: fix a number of build problems found on Solaris and NetBSD
- Use of nonportable <endian.h>
- Use of qsort_r
- Use of zlib without appropriate magic to pull in the binutils zlib
- Use of off64_t without checking (fixed by dropping the unused fields
  that need off64_t entirely)
- signedness problems due to long being too short a type on 32-bit
  platforms: ctf_id_t is now 'unsigned long', and CTF_ERR must be
  used only for functions that return ctf_id_t
- One lingering use of bzero() and of <sys/errno.h>

All fixed, using code from gnulib where possible.

Relatedly, set cts_size in a couple of places it was missed
(string table and symbol table loading upon ctf_bfdopen()).

955b06fa57 Don't crash is dwarf_decode_macro_bytes's 'body' is NULL, even when '!is_define'
Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1715008

On commit 7bede82892a06e6c26989803e70f53697392dcf9 ("Don't crash if
dwarf_decode_macro_bytes's 'body' is NULL"), I was too strict when
checking if 'body' is NULL: the check only comprised the case when
'is_define' is true.  However, the corruption of .debug_macro by
rpmbuild's "debugedit" also affects the case when 'is_define' is
false, i.e., when the macro is being undefined.

This commit improves the check and covers both cases now.  This has
been tested on Fedora 30 with a problematic debuginfo, and I don't see
a segfault anymore.

OK to push?
