As described in Issue 16849, the existing Tools::getUniqueName method
requires calling code to form a vector of existing names to be avoided.
This leads to poor performance both in the O(n) cost of building such a
vector and also getUniqueName's O(n) algorithm for actually generating
the unique name (where 'n' is the number of pre-existing names).
This has particularly noticeable cost in documents with large numbers
of DocumentObjects because generating both Names and Labels for each new
object incurs this cost. During an operation such as importing this
results in an O(n^2) time spent generating names.
The other major cost is in the saving of the temporary backup file,
which uses name generation for the "files" embedded in the Zip file.
Documents can easily need several such "files" for each object in the
document.
This update includes the following changes to use the newly-added
UniqueNameManager as a replacement for the old Tools::getUniqueName
method and deletes the latter to remove any temptation to use it as
its usage model breeds inefficiency:
Eliminate Tools::getUniqueName, its local functions, and its unit tests.
Make DocumentObject naming use the new UniqueNameManager class.
Make DocumentObject Label naming use the new UniqueNameManager class.
This needs to monitor DocumentObject Labels for changes since this
property is not read-only. The special handling for the Label
property, which includes optionally forcing uniqueness and updating
links in referencing objects, has been mostly moved from
PropertyString to DocumentObject.
Add Document::containsObject(DocumentObject*) for a definitive
test of an object being in a Document. This is needed because
DocumentObjects can be in a sort of limbo (e.g. when they are in the
Undo/Redo lists) where they have a parent linkage to the Document but
should not participate in Label collision checks.
Rename Document.getStandardObjectName to getStandardObjectLabel
to better represent what it does.
Use new UniqueNameManager for Writer internal filenames within the zip
file.
Eliminate unneeded Reader::FileNames collection. The file names
already exist in the FileList collection elements. The only existing
use for the FileNames collection was to determine if there were any
files at all, and with FileList and FileNames being parallel
vectors, they both had the same length so FileList could be used
for this test..
Use UniqueNameManager for document names and labels. This uses ad hoc
UniqueNameManager objects created on the spot on the assumption that
document creation is relatively rare and there are few documents, so
although the cost is O(n), n itself is small.
Use an ad hoc UniqueNameManager to name new DymanicProperty entries.
This is only done if a property of the proposed name already exists,
since such a check is more-or-less O(log(n)), almost never finds a
collision, and avoids the O(n) building of the UniqueNameManager.
If there is a collision an ad-hoc UniqueNameManager is built
and discarded after use.
The property management classes have a bit of a mess of methods
including several to populate various collection types with all
existing properties. Rather than introducing yet another such
collection-specific method to fill a UniqueNameManager, a
visitProperties method was added which calls a passed function for
each property. The existing code (e.g. getPropertyMap) would be
simpler if they all used this but the cost of calling a lambda
for each property must be considered. It would clarify the semantics
of these methods, which have a bit of variance in which properties
populate the passed collection, e.g. when there are duplicate names..
Ideally the PropertyContainer class would keep a central directory of
all properties ("static", Dynamic, and exposed by ExtensionContainer and
other derivations) and a permanent UniqueNameManager. However the
Property management is a bit of a mess making such a change a project
unto itself.

Menu texts in the Assembly WB are in title case without articles.
The following menu texts did not follow that 'standard':
* Insert a new part
* Create a Fixed Joint
This adds isNullOrEmpty string helper that cheks if string is... well
null or empty. It is done to improve readability of the code and better
express intent.
Fixes#16333.
Follow-up of #19487.
* The functions have been made nesting-aware. New objects are put in the same container (Group, Part) as the original objects. As a consequence for some operations the original objects must be in the same container as well.
* New objects receive the visual properties of the original objects. This is not always perfect. For example when upgrading to multiple wires there is currently no check to see which edge came from which orginal object. The fact that the `format_object` function is called from the Draft `make*` functions is problematic here. If construction mode is active `make_wire` puts new objects in the construction group and we don't always want that. This has been solved with a workaround (see 'cludge' in the code).
* The 'de-parametrize' downgrade option has also been enabled for features of PartDesign Bodies that have the `Profile` property.
* Before deleting objects there is a check to see if they are in use elsewhere (`InList` check). Base objects of arrays are not deleted if they are visible. If a PartDesign Body, or an object inside a Body is selected, the whole Body is deleted.
* The force options did not work for functions that take a single object.
* The `getShapeFromMesh` function in ArchCommands.py could return a solid that was not closed. A check for that has been added.
Its pretty helpful when developing to have multiple build directories
for different branches.
This adds such pattern to .gitignore to be able to have a sane Git
experience.
