Fix inconsistent output of prefix and bugs in 'show' command
cmd_show_list function implements the 'show' command.
cmd_show_list output is inconsistent: it sometimes shows a prefix
and sometimes does not.
For example, in the below, you see that there is a prefix before
each value, except for 'enabled'.
(gdb) show style
style address background: The "address" style background color is: none
style address foreground: The "address" style foreground color is: blue
style address intensity: The "address" style display intensity is: normal
enabled: CLI output styling is enabled.
style filename background: The "filename" style background color is: none
...
There are other inconsistencies or bugs e.g. in
the below we see twice insn-number-max, once with a prefix
and once without prefix : last line, just before the value of
instruction-history-size which is itself without prefix.
(gdb) show record
record btrace bts buffer-size: The record/replay bts buffer size is 65536.
record btrace cpu: btrace cpu is 'auto'.
record btrace pt buffer-size: The record/replay pt buffer size is 16384.
record btrace replay-memory-access: Replay memory access is read-only.
record full insn-number-max: Record/replay buffer limit is 200000.
record full memory-query: Whether query if PREC cannot record memory change of next instruction is off.
record full stop-at-limit: Whether record/replay stops when record/replay buffer becomes full is on.
function-call-history-size: Number of functions to print in "record function-call-history" is 10.
insn-number-max: instruction-history-size: Number of instructions to print in "record instruction-history" is 10.
(gdb)
Also, some values are output several times due to some aliases, so avoid outputting duplicated
values by skipping all aliases.
Now that the command structure has a correct 'back-pointer' from a command
to its prefix command, we can simplify cmd_show_list by removing its prefix argument
and at the same time fix the output inconsistencies and bugs.
