NetBSD emits:
warning: Warning: reference to the libc supplied alloca(3); this most likely will not work. Please use the compiler provided version of alloca(3), by supplying the appropriate compiler flags (e.g. not -std=c89).
and man 3 alloca says:
Normally, gcc(1) translates calls to alloca() with inlined code. This is not done when either the -ansi, -std=c89, -std=c99, or the
-std=c11 option is given and the header <alloca.h> is not included. Otherwise, (without an -ansi or -std=c* option) the glibc version of
<stdlib.h> includes <alloca.h> and that contains the lines:
#ifdef __GNUC__
#define alloca(size) __builtin_alloca (size)
#endif
It looks like alloca is a bad idea in modern C/C++, so we use
VLAs for C and std::vector for C++.
Further speedups to icu compilation, it is faster to run the
pre-generated configure scripts.
Ensure that the native protobuf installation only generates the required
libraries and binaries.
Disable qt compilation when running travis on windows. Qt is used for
lrelease, the travis recipe instead usese the a local installation of
lrelease.
Remove various packages and options from the travis recipe.
Update Readline to version 8.0. The previously used url 404'd sometimes,
use the official gnu ftp server instead.
Remove unused cmake config.
Building with docker is arguably easier and more familiar to most people
than either kvm, or lxc.
This commit also relaxes the back compat requirement a bit. 32 bit linux
now uses glibc version 2.0. Also, the docker shell could not handle gcc arguments
containing spaces, so the explicit '-DFELT_TYPE' declaration was dropped.
Lastly, this removes some packages from the osx descriptor.

The change made for v2 broke v1, and we have no way to know which
version we're serializing here. However, since we don't actually
care about space savings in this case, we continue serialiazing
both mask and amount.
RPC connections now have optional tranparent SSL.
An optional private key and certificate file can be passed,
using the --{rpc,daemon}-ssl-private-key and
--{rpc,daemon}-ssl-certificate options. Those have as
argument a path to a PEM format private private key and
certificate, respectively.
If not given, a temporary self signed certificate will be used.
SSL can be enabled or disabled using --{rpc}-ssl, which
accepts autodetect (default), disabled or enabled.
Access can be restricted to particular certificates using the
--rpc-ssl-allowed-certificates, which takes a list of
paths to PEM encoded certificates. This can allow a wallet to
connect to only the daemon they think they're connected to,
by forcing SSL and listing the paths to the known good
certificates.
To generate long term certificates:
openssl genrsa -out /tmp/KEY 4096
openssl req -new -key /tmp/KEY -out /tmp/REQ
openssl x509 -req -days 999999 -sha256 -in /tmp/REQ -signkey /tmp/KEY -out /tmp/CERT
/tmp/KEY is the private key, and /tmp/CERT is the certificate,
both in PEM format. /tmp/REQ can be removed. Adjust the last
command to set expiration date, etc, as needed. It doesn't
make a whole lot of sense for monero anyway, since most servers
will run with one time temporary self signed certificates anyway.
SSL support is transparent, so all communication is done on the
existing ports, with SSL autodetection. This means you can start
using an SSL daemon now, but you should not enforce SSL yet or
nothing will talk to you.
According to [1], the ios_base::streampos member type is deprecated, and
removed in C++17. This type was an alias for pos_type, which this commit
uses instead.
