Add a small stub which verifies whether /data/data/com.termux/files/usr is readable
into few important packages such like Bash or APT. If this check fails, e.g.
in case if binary was executed in program with different package name (non-Termux),
program will print warning and exit with error status immediately.
This should prevent use of prebuilt packages by third-party applications.
NOTE: for now it uses /data/data/com.termux/files/usr in reversed order to
prevent automatic "blind" patching with sed. Will replace with randomized
XOR-based variant in case if that measure won't be enough.
During repository updates & cleanup there can be a short period of time
when repository metadata is not consistent. There may appear an error
like
E: The repository 'https://termux.org/package stable Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
but it may not be clear for some users what can cause the issue.
This commit improves the situation a bit.
Usage of package manager as root has certain bad effects in Termux such as
messed up SELinux contexts and ownership. Root checks done in 'pkg' wrapper
are not reliable because one can execute 'apt' directly or with third-party
script downloaded from the Internet.
This commit adds user id check and if it found that uid is 0, apt will
refuse to do any work in root session. These checks done in such way so
they cannot be bypassed in any way unless command is executed as non-root
user.
Those who use Termux via ADB root shell should be able to switch to Termux
user id with command 'su' in order to have package manager working.
---
This change also affects the 'termux-info' utility:
* It will no longer use 'apt policy' to detect subscribed repositories. Each
source will be checked by script manually.
* Information will be copied to clipboard only if 'termux-api' is installed.
* Syntax error in timeout command is fixed: 'timeout' doesn't understand the
argument '-t'.
* Minor information entries reordering.
Reorganize patches for better understanding and ensure they are applied in
expected order.
Another changes:
* gnupg is now in recommends (used by apt-key).
* x11-repo is now in suggests.
* TCSAFLUSH patch is dropped because it is covered by one of NDK patches
where TCSAFLUSH value is replaced with TCSANOW.

they should accept boolean values which makes them easier to handle and
also makes their meaning clear.
build-package.sh should make decision based on variable's value but not on
whether it is set or empty.

Should fix following error:

That was a failed attempt to handle libiconv/libandroid-support upgrade issue.
Completely useless and therefore should be reverted.
Issue was solved by:
* 75436ef46f1e08b139110435204a3426babaf57d (libandroid-support pre-depends on dpkg)
* b35e4e4654b669292a51976e09c80b8a8780825a (dpkg will use busybox for tar and rm)
This reverts commit 1ab847733aeea81efee4fa852a2c7231c444fd2d.
