0de7b17d03 tui: Reset the scroll region when resizing. 
DECSLPP is explicitly documented as not affecting the scroll region. The
dtterm extension is not as well documented, but it is safer than not to
assume that it operates similarly.

This also eliminates a pointlessly repeated test from tui_scroll(). It
additionally uses a non-parameterized DECSTBM sequence when attempting
to reset back to whole-screen scrolling.

593af64943 tui: resize: use an extended terminal capability 
... rather than hardwiring the string and testing the terminal
type every time the screen is re-sized.

36d1fd0602 tui: Only use dtterm's extension where supported. 
This limits the use of dtterm's extension to DECSLPP to only those
terminal types where it is known to be supported.
Because it can be potentially understood as genuine DECSLPP
sequence, setting the number of lines to a number larger than 25,
which of course can cause confusion (especially if it is the width
parameter that results in this) only use it on terminals that are
known to support the dtterm extension.

rxvt (Unicode) also understands dtterm's extension.

a5a5c83608 api/vim: Fix nvim_list_runtimepaths 
It used to

1. Always omit last component in runtimepath.
2. Always omit trailing empty item and leave uninitialized memory in place of 
   it.

7b55d50bbd tui.c: Initialize TUI input component only once. (#6784) 
term_input_start should be called only once. This fixes a leak
introduced by af2e629be4.

Closes #6780

Steps to demonstrate memory leak:

    nvim -u NONE -i NONE --cmd $'function S()\nsuspend\nendfunction' --cmd 'inoremap <expr> X S()' --cmd 'call feedkeys("iX", "t")'

3efc82cbb2 Server: use uv_getaddrinfo() for $NVIM_LISTEN_ADDRESS 
This change implicitly adds IPv6 support.

If the address contains ":", we try to use a TCP socket instead of a Unix domain
socket. Everything in front of the last occurrence of ":" is the hostname and
everything after it the port.

If the hostname lookup fails, we fall back to using a Unix domain socket.

If the port is empty ("localhost:"), a random port will be assigned.

Examples:

  NVIM_LISTEN_ADDRESS=localhost:12345 -> TCP (IPv4 or IPv6), port: 12345
  NVIM_LISTEN_ADDRESS=localhost:      -> TCP (IPv4 or IPv6), port: random (> 1024)
  NVIM_LISTEN_ADDRESS=localhost:0     -> TCP (IPv4 or IPv6), port: random (> 1024)
  NVIM_LISTEN_ADDRESS=localhost       -> Unix domain socket "localhost" in current dir

40444e9186 main: Silence V522: potential NULL pointer dereference 
AFAIK there is no way NULL can be there, including from the line it points to.
Dunno what analyser was thinking, but dereferencing of `argv[0]` happened just
before `get_number_arg()` call: in `ascii_isdigit()` two lines above. And `idx`
cannot possibly be NULL ever, it comes from `&varname`, this could not ever give
anything, but a valid pointer.

2411b6f137 charset: Fix V695: dead branches 
Based on comments it appears that some non-printable characters intended to be 
shown as `|x` (0xA0..0xFE) and some as `~x` (0x80..0x9F, 0xFF, excluding 
previous). But this never happens because this is being catched by condition `c 
>= 0x80` above which makes them be represented as `<A0>`. Since I find this 
variant more useful and it additionally is backwards compatible (Vim does the 
same thing) I just dropped dead branches.
