Fixes a number of issues. From the changelog:
- Avoid getting stuck in a loop writing huge key files, reported by Bruno
Thomsen
- Avoid crash on exit due to cleaned up keys before last packets are sent,
debugged by Ronald Wahl
- Fix a race condition in rekeying where Dropbear would exit if it received a
still-in-flight packet after initiating rekeying. Reported by Oliver Metz.
This is a longstanding bug but is triggered more easily since 2013.57
- Ensure that generated RSA keys are always exactly the length
requested. Previously Dropbear always generated N+16 or N+15 bit keys.
Thanks to Unit 193
- Fix DROPBEAR_CLI_IMMEDIATE_AUTH mode which saves a network round trip if the
first public key succeeds. Still not enabled by default, needs more
compatibility testing with other implementations.
- Fix signal handlers so that errno is saved, thanks to Erik Ahlén for a patch
and Mark Wickham for independently spotting the same problem.
And at the same time get rid of the TIMEVAL_TO_TIMESPEC as dropbear provides a
fallback implementation if not available (and has done so since 2006).

Fixes two security issues:
- The Dropbear server could be made to consume large amounts
of memory because decompressed packet sizes weren't checked.
Depending on the OS and hardware this might be a denial of
service.
- Valid users could be identified due to timing variations.

Switch ECHOs to SEDs to avoid issues with defines changing after
sysoptions.h was included - and it's cleaner.
Enable hmac-sha2-256 and hmac-sha2-512 support for the full featured.

From the release notes:
Security: Fix use-after-free bug that could be triggered if command="..."
authorized_keys restrictions are used. Could allow arbitrary code
execution or bypass of the command="..." restriction to an authenticated
user.

Buildroot does not have wtmp or lastlog support by default so allow dropbear
to be configured to stop using them and hence to stop generating system log
error messages.

Thanks to the pkgparentdir and pkgname functions, we can rewrite the
AUTOTARGETS macro in a way that avoids the need for each package to
repeat its name and the directory in which it is present.
[Peter: pkgdir->pkgparentdir]

Changelog @ http://matt.ucc.asn.au/dropbear/CHANGES
Since some build-time defaults have changed that make dropbear somewhat
bigger we introduce a new option to optimize dropbear for size.

The recent conversion to new-style hooks didn't actually enable the
xauth tweaking. Also rename to FIX_XAUTH as it just tweaks the path,
it doesn't disable anything.

Add option to disable reverse DNS lookups on client connection, as
connections otherwise stall until DNS times out in configurations without
working reverse DNS.

Configure misdetects this as no, but the result is not used for anything.
Unfortunately it breaks the build for other packages also checking for
struct sockaddr_storage (like rsync) when using a shared config cache,
so force it to yes.

A C library will have been built by the toolchain makefiles, so there is no
need for packages to explicitly depend on uclibc.

The -D option to install only works portably when the destination is
a file. Specifying the filename avoids the following build error (at
least on some hosts):
"/usr/bin/install: cannot overwrite directory `/tmp/buildroot/
project_build_foobar/uclibc/root/etc/init.d' with non-directory"

they should be configured with --prefix=/usr and we then need to use
make DESTDIR=$(STAGING_DIR) install to get things installed into the
staging directory. The current situation for many packages, which use
--prefix=$(STAGING_DIR) results in the staging_dir paths getting compiled
into the binary itself.
This also adds in a pile of libtool fixups. Between broken pkgconfig,
broken libtool handling, and broken --prefix settings, its a wonder
things have worked as well as they have up till now.
