The NSFastEnumerator protocol in Objective-C works like this:
1. A selector is called on the collection in question, where we give the
native method a pointer to a state structure. Upon return, the state
structure will have two important pointers: one to a C array with the
pointers to enumerate, and another pointer that points to a value
determining whether the collection was modified since enumeration started.
2. In the original managed implementation, we'd store the state (a struct) as
an instance field of NSFastEnumerator.
This works fine... most of the time. Unfortunately most of the time isn't good
enough, because this may happen:
a. The native iterator function might store a pointer into the state structure
itself as the pointer to check for a modified collection.
b. The GC runs, and moves memory around.
Now suddenly the pointer we have to read to check if the collection was
modified is pointing to the previous location of the state structure, which
could be anything or anywhere, and the app subsequently tries to summon Murphy
from his pantheon in the sky (admittedly with limited success).
The fix is to use native memory (which the GC won't move around) to store the
enumeration state.
Also optimize memory usage a little bit by allocating one big blob for both
the state and the array of pointers we pass to the native iterator method.

Return early after a failure, in order to fix a nullability problem where the
out variable from a method call can be null if the function returns false - in
which case we can't keep doing things, we need to return, because the
subsequent code doesn't handle the potential null value from the out
parameter.
While this value isn't used directly in xharness, we can add a
'skip-packaged-macos-tests' label for a PR, which xharness will try to match
with a test label, so the test label must exist, otherwise all tests will
fail.
In our localization process, the Loc team builds the translations (in
the not-user-readable .lcl files) and merges them into the
'Localization' branch from a 'Lego/...' branch. After this happens, our
'Get Localization Translations' github action takes that commits and
creates a PR into main with those changes. It is really important that
this github action works because we will later delete the 'Localization'
branch and create a new one from the 'main' branch so that the branches
stay in sync.
There worked fine, but there is now a 'isDeletePrSourceBranchSelected'
input to the OneLocBuild task that defaults to true that deletes the
'Lego/...' branch right after the commit to 'Localization' is made. Due
to this, the github action cannot bring the commit to 'main' because the
'Lego/...' branch no longer exists.
The hope is that setting this input to false will successfully not
delete the 'Lego/...' branch allowing the rest of the flow to be
uninterrupted.

The -gcc_flags in the extra mtouch/mmp arguments can either be of the format
'-gcc_flags=<value>' or '-gcc_flags <value>'. Previously we only parsed the
former correctly, and now fix the parsing logic to handle the latter version
correctly as well.

When the autoformatter runs into the '%...%' pattern in *.cs files, it
will re-format the text (to '% ... %'), but that breaks our text replacement
logic. So instead use a valid C# identifier as a replacement token, in which
case the autoformatter won't confuse our replacement logic.
Don't add a dot after showing another exception message, because that another
exception message might also add a dot.
Example:
> An exception occurred while trying to invoke the function System.Void VisualStudioMac.AppDelegate.DidFinishLaunching (Foundation.NSNotification): Object of type 'CoreLocation.CLLocationManager' cannot be converted to type 'Foundation.NSNotification'..

This PR addresses https://github.com/xamarin/xamarin-macios/issues/10275
`actool` can set an application's "Global" color set, overwriting the system defaults. XCode sets this as "AccentColor," but when we call it directly, we don't pass in anything. This means a user cannot overwrite this setting themselves unless they rewrite the ACTool task.
This PR adds support for the "AccentColor" property to set the accent color.
To use this:
- Create a new Asset Catalog or use the default.
- Add a new ColorSet.
- Set the "AccentColor" property in the project file:
<PropertyGroup>
<AccentColor>AccentColor</AccentColor>
</PropertyGroup>
You should now see the colors reflected in the application.
We recently tried to fix NSDate's conversion operators with DateTime
(3c65ab1756), but unfortunately a corner case
was missed.
The new approach in the above-mentioned commit would get the individual
date/time components for a given date and use the appropriate constructor for
the other type to re-construct the date/time in question.
However, one case was missed: when converting from NSDate to DateTime, we'd
get a fractional number of milliseconds. This fractional number could be
something like 999.99 milliseconds, and when converting that to the int the
DateTime constructor expected for the number of milliseconds, then DateTime
would throw an exception, because the number of milliseconds could only be
between 0 and 999.
I've solved this by not using floating-point math in the computations. We're
now getting the number of nanoseconds from the NSDate (which is a natural
number, and represents the total number of nanoseconds less than a whole
second), and then converting that to the number of milliseconds, microseconds
and ticks that can be used with DateTime using integral math. Unfortunately
DateTime doesn't have a constructor that takes the remaining number of ticks
after all the other fields have been provided, but that can be added
afterwards.
I've also made a few other improvements:
* Improve the validation for the NSDate -> DateTime conversion to detect BC
dates by using the NSDate's Era component (to throw because DateTime only
supports AC dates). Also don't allow a tick later than year 10.000 (DateTime
only supports up to a tick before year 10.000) - but explicitly support
exactly year 10.000, and convert it to DateTime.MaxValue (this is because
due to precision errors NSDate can't actually express 'a tick before year
10.000', it ends up being rounded up to year 10.000 exactly). This means
there are no more magical values in the range validation checks.
* Increase precision in the DateTime -> NSDate conversion by starting with the
sub-second amount of ticks from the DateTime instance (instead of the number
of milliseconds). This allows us to compute the nanoseconds NSDate expects
with much higher precision.
* More tests!

This is the pull request automatically created by the OneLocBuild task
in the build process to check-in localized files generated based upon
translation source files (.lcl files) handed-back from the downstream
localization pipeline. If there are issues in translations, visit
https://aka.ms/ceLocBug and log bugs for fixes. The OneLocBuild wiki is
https://aka.ms/onelocbuild and the localization process in general is
documented at https://aka.ms/AllAboutLoc.
Unify the code for the following constructors:
* NSAttributedString (NSData data, NSDictionary options, out NSDictionary resultDocumentAttributes, ref/out NSError error);
* NSAttributedString (NSUrl url, NSAttributedStringDocumentAttributes options, out NSDictionary resultDocumentAttributes, ref/out NSError error);
* NSAttributedString (NSData data, NSAttributedStringDocumentAttributes options, out NSDictionary resultDocumentAttributes, ref/out NSError error);
These functions use 'ref' arguments instead of 'out' arguments for mobile
platforms (likely due to the generator not having proper 'out' parameter
support when these functions were implemented), so improve to use 'out'
parameters in XAMCORE_5_0 (and macOS, where they already use 'out'
parameters).
Also fix nullability.
