APKs have been created with GNU tar so far, which uses the
GNU extensions for long names. In order to increase portability
support the standard header's 'prefix' portion in case
the GNU extensions are not present.
Depending how the directory entries are ordered, the cached dir
instance might not have been updated correctly. This has not been
a problem as the entries have been ordered, but is now triggered
on ppc.
The value from tar header is unsigned int; keep it casted to
unsigned int and size_t instead of (signed) int, otherwise
the comparisons fail to do their job properly. Additionally check
entry.size against SSIZE_MAX so the rounding up later on is
guaranteed to not overflow.
Fixes CVE-2017-9669 and CVE-2017-9671.

- rework the progress bar a little bit, basically removing the [ and ] to give a more
modern aesthetic.
- if utf-8 locale is enabled, use unicode codepoint 0x2588 instead of # to give the
progress bar a nicer look.
- if APK_PROGRESS_CHAR environment variable is defined, use the character defined there
for the progress bar.
This is useful for requirements such as: python3=~3.6, which would match python3-3.6.[0-9].
This implementation should in theory be backwards compatible with the implementation in Adelie.
Fixes regression from commit 5ba27c90 which caused stdio
buffering issues now that output is split to stderr/stdout.
See also commit 51737872 for some of the history.
Fixes#7107
On some (probably buggy) terminals, printing up to the rightmost column
may end up with the terminal issueing a newline (probably due to putting
the cursor at the next char -> new line).
Some other progress bars avoid it by not reaching the rightmost column.
Shorten the bar width from term-width - 7 to -8 (the 7 are "xxx% []").
fixes#5616
The original intention was not use unnecessary space on tmpfs
e.g. if the cache directory is a mount point, but accidentally
left unmounted. But there are valid cases when packages are
intentionally wanted to be cached on tmpfs. If caching is not
desired, the user can just remove the cache directory.
This allows for instance integration of etckeeper
[TT: Reorganized code a bit, and modified to use single
directory commit_hooks.d with argument for script of stage.]
Currently apk only knows about powerpc and ppc64. I am adding support for ppc64le.
ppc64le is the based on the ABI v2, which defines the endianess as little,
while ppc64 is based on the first 64-bits ABI.
It is unreasonable to assume that all package writers would except
to reset umask themselves. It's done currently in most packages,
but we had first issue of this kind recently, so better just reset
umask.
