lnav v0.12.3 released

[lnav support]

lnav v0.12.3 has been released:

https://github.com/tstack/lnav/releases/tag/v0.12.3

Features:

* Files that contain a mixture of log messages from separate

  services (e.g. docker logs) can now be automatically

  de-multiplexed into separate files that lnav can digest.

* The `log_opid` column on log vtables can now be `UPDATE`d

  so that you can manually set an opid on log messages that

  don't have one.  Setting an opid allows messages to show

  up in the timeline view.

* The Files panel now has a details view on the right side

  that shows extra information about the selected file.

  You can look here for details of why lnav selected a

  particular log format.

* Add support for GitHub Markdown Alerts.

* Added the `:xopen` command that will open the given paths

  using an external opener like `open` or `xdg-open`.

* Clicking on a link in a markdown file will open the Actions

  with the following options:

  - opening the link target in lnav or, if it's an lnav script,

    executing the script;

  - opening the target with `:xopen`;

  - or, copying the link to the clipboard.

* Added a `crash upload` command to the management CLI that will

  upload crash logs to a server for analysis.

* Added a `:set-text-view-mode` command that controls whether

  file contents, such as markdown, are rendered or shown in

  their raw state.

* Text files with lines longer than 1024 characters will be

  automatically pretty-printed.  You can revert to the raw view

  using the `:set-text-view-mode` command.  The character limit

  can be adjusted with the

  `/tuning/textfile/max-unformatted-line-length` configuration

  setting.

* Added a `pretty_print()` SQL function that provides the same

  functionality as the PRETTY view.

* Keymap definitions can now bind to a function key using an

  identifier that starts with `f` followed by the number of the

  function key.

* Added log formats for the `env_logger` and `simple_logger` Rust

  crates.

* Timestamp formats can now use `%j` to capture day-of-year values.

Interface Changes:

* The "Gantt Chart" view has been renamed to "timeline."

* In the timeline view, pressing `ENTER` will focus on

  the preview pane, so you can scroll through messages

  with the selected Op ID.

* With mouse mode enabled, `CTRL` can be used as an alternate

  to `SHIFT` when clicking/dragging in the main view to

  highlight lines.  A few terminals capture shift+clicks as a

  way to select text and do not pass them to the application.

* Clicking on an internal link in a Markdown document will move

  to that section.

Bug Fixes:

* Log messages in formats with custom timestamp formats were

  not being converted to the local timezone.

* The timezone offset is now shown in the parser details

  overlay for log messages.

* If a theme does not define `cursor-line` or `selected-text`

  styles, the styles from the default theme will be used.

* The first argument to a script is now the full path of the

  script and not just the script name.

Maintenance:

* You can now do an `UPDATE` on the `lnav_top_view` SQL view.

  This makes it easier to write queries that manipulate the

  current view.

* Upgrade to C++17
