Document missing libgeom functions

[romain]

Summary

Add a quick description of the geom_getxml(3), geom_xml2tree(3),
geom_gettree(3) and geom_deletetree(3) functions provided by libgeom and are
not documented in libgeom(3).

A few line breaks are needed after sentence stops. You can use textproc/igor to check for this and other common man page errors.
Additionally, you need to bump the .Dd to the current date as this is a content change.
Thanks for adding these descriptions.

lib/libgeom/libgeom.3

299

You need to make a line break after a sentence stop.

310

Another line break is needed here.

321

An another line break here.

[romain]

Add missing line breaks, update date and fix a typo found by igor(1).

[romain]

These issues are now fixed, thank you for spotting them.

igor(1) still reports the following:

libgeom.3:299:contraction:OID, and returns [it's] value.

I guess it's a false positive?

[bcr]

Not sure about this, a native speaker can probably clear this up.

"a bunch of" is a little more colloquial than we average in man pages; "allocates the needed data structures" might be better.

Also, "fills in" does not need a hyphen.

330

Either "The .Fn geom_deletetree function" or just ".Fn geom_deletetree", but not halfway in between.

Address issues spotted by @bjk

@bjk thank you for the feedback, this should be fixed now!
