X-FIRMWARE-VERSION gets set to the content of the file referenced by UCI setting "autoupdater.settings.version_file"
If "autoupdater.settings.version_file" is unset X-FIRMWARE-VERSION is
omitted
If an autoupdater long option (prefixed with '--') are unknown then a segmentation fault occurs.
Example:
root@node:~# autoupdater --xyz
Segmentation fault
[Matthias Schiffer: changed sentinel syntax]
This fixes ordering for the following patterns:
* 1.0 < 1.0a
* 1.0a < 1.0ab
* 1.0a < 1.0a1
Note that trailing zeros are still ignored (1.0 == 1., 1test0 == 1test),
which matches the behaviour of dpkg and opkg.
Version strings with the same prefix, e.g. "1.0" and "1.0~pre", or even
"1.0" and "1.0.1" were considered equal. This is a regression in the C
autoupdater rewrite.
Give the user a better error message when allocations fail by using our
checked allocation functions.

[Matthias Schiffer: squash, use safe_realloc]
safe_malloc() and safe_realloc() are wrappers around malloc() and realloc()
than abort the process if the memory allocation fails.

[Matthias Schiffer: add safe_realloc()]
Previously the return value of uci_alloc_context was not checked leading
to a possible null ptr dereference

[Matthias Schiffer: use abort()]
Previously supplying an invalid url for download would result in
uclient_new returning NULL and crash the autoupdater as soon as
cl->priv is accessed.

This new version of the autoupdater is implemented in C instead of Lua,
allowing us to interface with libuclient (HTTP downloads) and libecdsautil
(signature checks) directly instead of spawning external processes,
saving RAM and making error handling more robust.
