doc: Update build-openbsd for 0.13.0+ and OpenBSD 5.9
- Python 3 now supported. - Bump boost version to 1.61 - one boost patch no longer needed. - All checked with OpenBSD 5.9, except for the clang part, I left this as-is for someone adventurous. - Mention overriding resource limits, OpenBSD's default ulimit does not suffice for building Bitcoin Core with gcc 4.9.3.

The default C++ compiler that comes with OpenBSD 5.7 is g++ 4.2. This version is old (from 2007), and is not able to compile the current version of Bitcoin Core. It is possible to patch it up to compile, but with the planned transition to C++11 this is a losing battle. So here we will be installing a newer compiler.

### Resource limits
|
||||
|
||||
The standard ulimit restrictions in OpenBSD are very strict:
|
||||
|
||||
data(kbytes) 1572864
|
||||
|
||||
This is, unfortunately, no longer enough to compile some `.cpp` files in the project,
|
||||
at least with gcc 4.9.3 (see issue https://github.com/bitcoin/bitcoin/issues/6658).
|
||||
If your user is in the `staff` group the limit can be raised with:
|
||||
|
||||
ulimit -d 3000000
|
||||
|
||||
The change will only affect the current shell and processes spawned by it. To
|
||||
make the change system-wide, change `datasize-cur` and `datasize-max` in
|
||||
`/etc/login.conf`, and reboot.
|
||||
|
||||
### Building Bitcoin Core
|
||||
|
||||
**Important**: use `gmake`, not `make`. The non-GNU `make` will exit with a horrible error.
