Subject: [PATCH] Build a temporal value from an array of temporal values
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MEOS reads an array of its own values through a pointer to the first element
and a count — `tsequence_make`, `tsequenceset_make`, `temporal_merge_array`
and the trgeometry twin of each. The object layer takes that as one C# array:
the wrappers' pointers are gathered into an `IntPtr[]` and pinned across the
call. The pin lasts exactly that long because the array is the caller's
throughout — `tsequence_make_free` is the twin that takes ownership, and it
does so by calling `tsequence_make` and then `pfree_array` on the array it
passed, which is sound only if `tsequence_make` neither frees nor retains it.
Eight constructors reach the object layer that way, 611 methods against 607.

The length parameter never appears in the C# signature, so it cannot disagree
with the array. That also settles which parameter is an array at all: the
length is named `count`, while a parameter named `n` is the index of the `*_n`
accessors, whose pointer is the receiver and no array — reading `n` as a
length turns `trgeometry_instant_n(temp, n)` into a call passing the
receiver's own length.

Three tests: a sequence made of three instants reads back as the text of all
three, merging two sequences answers four instants across two sequences, and
an empty array reaches MEOS as the invalid argument it is.
