Mike Kaganski cfff893b9c Move unit conversion code to o3tl, and unify on that in more places

This also allows to easily add more units, both of length and for other
unit categories.

The conversion for "Line" unit (312 twip) is questionable. Corresponding
entries in aImplFactor in vcl/source/control/field.cxx were inconsistent
(45/11 in; 10/13 pc; 156/10 pt). They were added without explanation in
commit c85db62602. I haven't found a spec
of the unit (https://en.wikipedia.org/wiki/Line_(unit) is not specific).
I used the definition based on "by pt", "by mm/100", "by char" (they all
were consistent); "by pc" seems inverted; "by twip" was half as much.
This accepted conversion makes unit test for tdf#79236 pass.

Very basic template functionality, a bit like boost or stl, but specific to LibO

o3tl stands for "OOo [o3, get it?] template library"

From [http://blog.thebehrens.net/2006/01/15/update-cow_wrapper-is-available-now/]
The scope for o3tl is admittedly kind of ambitious, as it should contain "...very basic (template)
functionality, comparable to what's provided by boost or stl, but specific to OOo (what comes to mind
are e.g. stl adapters for our own data types and UNO, and stuff that could in principle be upstreamed
to boost, but isn't as of now)."

== Class overview ==

[git:o3tl/inc/o3tl/cow_wrapper.hxx]
A copy-on-write wrapper.

[git:o3tl/inc/o3tl/lazy_update.hxx]
This template collects data in input type, and updates the output type with the given update functor,
but only if the output is requested. Useful if updating is expensive, or input changes frequently, but
output is only comparatively seldom used.

[git:o3tl/inc/o3tl/range.hxx]
Represents a range of integer or iterator values.

[git:o3tl/inc/o3tl/vector_pool.hxx]
Simple vector-based memory pool allocator.

[git:o3tl/inc/o3tl/functional.hxx]
Some more templates, leftovers in spirit of STLport's old functional
header that are not part of the C++ standard (STLport has been
replaced by direct use of the C++ STL in LibreOffice).
