The v3 format will not require the hash, but synthesize it to the
DB so v3 packages can get installed properly.

fixes #10785

The apk_fsdir_file_digest() servers dual purpose: to calculate
the checksum, but also to determine if the file exists. Move
it's error check where it originally was.

fixes #10791

fixes #10778

Symlinks should use the real target filename instead of
the temporary extraction name.

The "untrusted" error is higher priority than malformed package.
But given that we expect valid .apk or index as argument, the
untrusted error is likely more accurate than having malformed
package.

ref #10788

Remove the APK_REPOSITORY_CACHED bit from dependencies only
packages (that is, installed_size == 0). For fetch, the problem
is that apk_db_select_repo() would return the cache repository,
but the package would not be there. Update also the locations
needed to handle these packages correctly without the cached
repository bit being set.

The adb object for apk_pkg_from_adb() was changed in commit 7d6de220
"database: support loading v3 indexes" which also addressed the broken
site in question but omitted updating the argument.

fixes #10783

Always return the original length; not the one with trailing '/'
amended.

fixes c60b7424 "optimize apk_pathbuilder_pop to get the old length"
ref #10784

The apk_istream is null for zero length files, and needs
special handling.

fixes #10784

avoids memrchr

give a fake trust root allowing anything. adbdump code will verify
and dump each signature individually.

by adding an abstraction layer to the file system

When extraction failed, the user has had no opportunity to edit
any files. Just clean up.

fix also the progress callback on uvol extraction

Report also version numbers as invalid if there's more than 18
digits.

fixes #10774

and fix the error code if untrusted adb is seen

apk_extract_file() already calls unlink if the error is fatal.

Without this header the build fails when used as a OpenWrt build
dependency.

Make sure we always have valid struct apk_trust * for code using it.

Load the signing keys directly when being specified to produce
sane error message if loading them fails.

In most places where pointer can be an 'error' it cannot be null
pointer. Further, in those cases just calling PTR_ERR() is not enough
to handle the null case. Simplify code by removing this case.

If NULL case needs to be handled, it's better to add separate check
and return fixed error code in that case.

- check magic field for 'ustar' on read
- harden get_octal to report errors on non-octal characters
  (e.g. GNU base256 encoding), fixes #10757
- fix mtime and size octal fields to not have zero terminator

fixes #10762

fixes #10759

'is' is null for directories

Directories are handled specially in package installation code, but
extract applet uses also apk_extract_file() to create directories.
These should not be unlinked as that fails with unexpected error code
terminating the extraction.

Unbreak handling of base 16 in fetch_parseuint(). It is used
only in http chunked mode handling.
