Use GQueue instead of GList to store listbox entries.
g_list_append() function is slow because it uses g_list_last()
internally to traverse from the beginning to the end of a list, so
forming a list of results has O(n*n) complexity instead of O(n).
GQueue contains pointers to head and tail of list and list length.
So in this case we don't need seach end of list every time when we
want append listbox entry to the listbox.

Optimization is based on examining file size and time of the last status
update. This is synchronous and is based on assumption that relatively
small files are quickly processed even on slow hardware so if refresh
timeout expires during their processing, the delay couldn't be noticed
by human. Therefore only rather big files have to be reported
unconditionally, and others - only if there is a match in this file or
if timeout expires.

Gets rid of get_line_at() function that was called only at one place and
was tightly coupled with caller function. It allows to perform some
minor optimizations, and as a result improve search time by 8%.

Do not override global precmd() funcation on Zsh. Define new _mc_precmd()
function and add it to precmd_functions array instead. This also effectively
fixes race condition with pwd call on Zsh, which may lead to empty prompt in mc.

Per Zsh documentation last command prefixed with space lingers in the
internal history until the next command is entered before it vanishes.
To make it vanish right away, type a space and press return.

If you navigate in your shell to a directory containing symlinks and
then start mc, mc will show the canonical path instead. It would be nice
to make it show the directory with the symlinks.
Example: in your shell execute these:
user:~$ mkdir -p /tmp/a/b /tmp/x ; ln -s /tmp/a/b /tmp/x/y
user:~$ cd /tmp/x/y
user:/tmp/x/y$ mc
In mc you'll find yourself in /tmp/a/b, though it'd be nicer to see
/tmp/x/y at the top, and correspondingly navigating to the parent would
take you to /tmp/x.
If you start bash or zsh from /tmp/x/y, the new instance will start
displaying the working directory as such. They do this via the PWD env
variable. On one hand, they set and maintain PWD to point to the current
directory, using the path as specified by the user (possibly containing
symbolic links). On the other hand, they check its value at startup. If
$PWD points to the same physical directory as the actual working
directory then they use this value. If $PWD points somewhere else then
it's simply ignored (so it's a hint only as to which symlinks to use to
get to the working directory, but never alters the actual cwd).
Now mc also does the same at startup (with respect of "Cd follows
links" option). Relative directories specified in the command line are
applied after possibly replacing the canonical cwd with $PWD. This way
for example
user:/tmp/x/y$ mc . ..
opens two panels in /tmp/x/y and /tmp/x instead of /tmp/a/b and /tmp/a
(whereas /tmp/x is actually a different directory than /tmp/a).

In mc-4.7.x.x selection was reset on CK_Store (copy to buffer).
In mc-4.8.x (4.8.11 and older) it is not.
Now this behavior is configurable using editor_drop_selection_on_copy
key in the ini file.

Most applications require the line number to precede the filename,
with apparently 'vim' and 'mcedit' being the only exceptions
(they accept both possible orders). E.g. 'emacs +10 /etc/services'
opens that file at line 10, but 'emacs /etc/services +10' simply
ignores the line number.

* 3051_cleanup: (27 commits)
Use AC_HEADER_MAJOR.
Don't use g_memmove().
Fix use of uninitialized memory in sigaction structure.
Clarify usage of MSG_IDLE in mcedit.
Fix search in internal viewer in case of nroff mode.
Use g_list_free_full().
Use g_slist_free_full().
Fix directory content counting before file operation.
(me_remote): don't use undefined _GL_UNUSED.
(file_mask_dialog): don't call tilde_expand() because vfs_path_from_str() returns an absolute path.
Fix reloading of the root directory.
Reduce cppcheck warnings (style) in src subdirectory.
Clarify usage of WPanel widget.
Rename structures:
Reduce cppcheck warnings (style) in lib subdirectory.
cppcheck: reduce variable scope.
Use UTF8_CHAR_LEN instead of a magic number
(lcsubstr): fix memory deallocation.
(panel_get_field_by_title): fix memory leak.
(sftpfs_open_file): fix memory leak.
...
Instead of checking for sys/mkdev.h headerfile, there is the
AC_HEADER_MAJOR helper for how to get major(), minor(), makedev().
Sinc with GLib efb1701bf3baf6f5b05fd1a7a5a4ff990a7dc460.
