Termux will check if termux files directory `/data/data/com.termux/files` has rwx permission access before installing bootstrap or starting terminal. Missing permission will automatically be set if possible. The `/data/data/com.termux` directory will also be created if it did not already exist, like if android did not already create it.
Users will now also be shown a crash notification if they attempt to start termux as a secondary user or in a work profile with info of the "alternate" termux files directory `/data/user/<id>/com.termux` set by android and the profile owner app if running under work profile (not secondary user). A notification will also be shown if the termux files directory (not "alternate") is not accessible.

Previously in (32135025) support was added with `disable-terminal-margin-adjustment` `termux.properties` property to disable terminal margin adjustment in case in causes screen flickering or other issues on some devices. It has now been removed in (7aefd943) and moved to Termux Settings since if it causes issues at startup and users can't access `termux.properties` file from the terminal, they will have to use SAF or root to access it, which will require an external app.
Users can set the value from the `Termux Settings` -> `Termux` -> `Terminal View` -> `Terminal Margin Adjustment` toggle. The `Termux Settings` can be accessed from left drawer in termux and from the android launcher shortcut for Termux Settings, usually accessible by long holding on Termux icon.
This would happen when soft keyboard was to be disabled or hidden at startup and a hardware keyboard was attached and user started typing on hardware keyboard without tapping on the terminal first.
The crash was reported for `Microsoft Surface Duo`, which would affect some samsung and other devices as well, mainly dual screens/foldables. It was caused by androidx:window library that has been used by termux-shared since v0.115 having a typo in its proguard rules which didn't stop the removal of the required method for release builds (not debug) by proguard.
The library has been patched and fix should be available on next version but doing an emergency patch now for termux as well.
For people who are getting the crash should set `disable-terminal-margin-adjustment=true` in `termux.properties` created as per instructions in the link below and then start termux again and see if it fixes the issue. If you had termux installed before updating, you should be able to directly access the `~/.termux/termux.properties` file with SAF.

APKs for each architecture and a universal APK that is compatible for all architectures will now be available from Github Actions page from the workflow runs labeled `Build`. The APKs will be available as zips under the Artifact section named `termux-app-*`.
Architecture specific APKs can be used by users with low disk space since F-Droid releases are universal (since it doesn't support split APKs #1904) and their install+bootstrap installation size is ~180MB instead of ~120MB if an architecture specific APK is used.
This should also reduce bandwidth usage and download time for debug builds users if they download an architecture specific zip instead of the universal one.

Logger was updated to get suppressed exceptions by calling `Throwable[] getSuppressed()` but `printStackTrace()` would already log them, even though shortened stacktrace with `... n more` notation, but this should be enough for debugging since main throwable stacktrace should have enough class line info. Manually logging full suppressed stacktraces would likely trigger `LOGGER_ENTRY_MAX_PAYLOAD` and split the message into multiple log entries and also duplicate the suppressed stacktraces, so best revert this unless ever necessary.
Create the TermuxCrashUtils class that provides the default path and app for termux instead of hardcoding it in CrashHandler. TermuxCrashUtils can be used by termux plugins as well for their own usage or they can implement the CrashHandler.CrashHandlerClient if they want to log to different files or want custom logic.
Changing the license for non-termux utils from GPLv3 to MIT so that they can be used by other termux plugin apps or apps that may be released under a different license. Termux is already using a lot of libraries that are not GPL and such general utils shouldn't be restrictive any ways.
Moreover, `TermuxConstants` and `TermuxPropertyConstants` should be MIT licensed as well so that other non-FOSS or non-GPLv3 apps can use them, like for `RUN_COMMAND` intent.
Any code not listed in exceptions of `LICENSE.md` files is still under GPLv3, mainly termux specific code and it will and should remain that way.
All code in files whose license is changed was authored by me as far as I can tell, but if any code in them is not that I missed, let me know, so that changes can be made since I can't and won't change the license of code authored by someone else. If some other objection is raised, let me know too.
Future contributors should check the `LICENSE.md` files and see if they are okay with contributing code as MIT and if they are not, then they should create separate file/package in termux-shared.
The user can add `terminal-onclick-url-open` entry to `termux.properties` file to enable opening url links in terminal transcript on click or on tap. The default value is `false`. So adding the entry `terminal-onclick-url-open=true` to `termux.properties` file will enable url opening. Running `termux-reload-settings` command will also update the behaviour instantaneously if changed.
This commit just adds the property and doesn't implement the functionality. That will later be merged from #2146.
The user can add `disable-terminal-margin-adjustment=true` entry to `termux.properties` file to disable terminal view margin adjustment that is done to prevent soft keyboard from covering bottom part of terminal view on some devices. Margin adjustment may cause screen flickering on some devices and so should be disabled. The default value is `false`. So adding the entry `disable-terminal-margin-adjustment=true` to `termux.properties` file will disable margin adjustment. Exit termux and restart for changes to take affect after updating value.
In case e5a9b99a did not fix screen flickering issues for #2127, then this can be used to disable it. Closes#2127.
