[FFe] Sync geos 3.7.0 from Debian unstable

[Darafei Praliaskouski]

https://tracker.debian.org/news/986587/accepted-geos-370-1-source-amd64-all-into-unstable/

Please sync geos 3.7.0-1 from Debian unstable (main).

Explanation of FeatureFreeze exception:

PostGIS 2.5.0 that will be released together with PostgreSQL 11 depends on new features in GEOS 3.7.0 (GEOSFrechetDistance).

Changelog explanation:
 - New C library methods GEOSDistanceIndexed, GEOSCoordSeq_isCCW, GEOSGeom_getXMin, GEOSGeom_getXMax, GEOSGeom_getYMin, GEOSGeom_getYMax, GEOSFrechetDistance, GEOSReverse, GEOSGeomGetZ. Do not affect software that was not using them in 3.6.
 - C API is stable. Only C++ ABI changed.
 - Added usage warnings for C++ API. Warning was actually added 2 years ago, most of popular software dealt with it.
 - GEOS adopted C++11.
 - Fixed crashes in AbstractSTRtree::query, GEOSIntersection, GEOSUnion on empty geometry elements.
 - GEOSClipByRect infinite loop fixed. Is currently exploitable as DoS on PostgreSQL/PostGIS.
 - GEOSSnap now properly handles interrupting. This lets query timeout in PostgreSQL/PostGIS work with it.

Only one reverse-dependency:
libossim1

I suspect the SONAME change has been done just because C++ symbols are hard to track, and they like to keep the number equal to upstream release.

Package builds fine, and also the only reverse-dependency

You can see ongoing builds on ppa:costamagnagianfranco/locutusofborg-ppa

(the request comes from postgis upstream FWIW)

We don't have postgres 11 in cosmic though. What is the plan there?

I think we should sync postgresql-11 from debian, but having the toolchain "ready", will be beneficial for people installing from ppa or building by themselves.
(postgresql-11 is not stable, and it shares libecpg-dev with previous postgresql releases, so sync is no-go)

[Darafei Praliaskouski (komzpa-gmail)]

Postgres 11 is expected be released in roughly same dates as Cosmic itself.

For xx.10 Ubuntu releases it's usually installed via PGDG-maintained Apt repositories, https://wiki.postgresql.org/wiki/Apt. However, they don't ship all the dependency tree, relying on distro packages for things like GEOS.

I'm closing this old Feature Freeze request. geos 3.7 (and Postgres 11) will be in Ubuntu 19.04 but didn't make it in for Ubuntu 18.10.
