random: Fix γ-section implementation for Randomizer::getFloat() (#12402)

The reference implementation of the "Drawing Random Floating-Point Numbers from
an Interval" paper contains two mistakes that will result in erroneous values
being returned under certain circumstances:

- For large values of `g` the multiplication of `k * g` might overflow to
infinity.
- The value of `ceilint()` might exceed 2^53, possibly leading to a rounding
error when promoting `k` to double within the multiplication of `k * g`.

This commit updates the implementation based on Prof. Goualard suggestions
after reaching out to him. It will correctly handle inputs larger than 2^-1020
in absolute values. This limitation will be documented and those inputs
possibly be rejected in a follow-up commit depending on performance concerns.

PGSQL: Allow unconditional selection in pg_select

Previously, pg_select did not allow unconditional selection, where an
empty ids array would result in a function failure.

This patch implements two changes:
- Make the ids array an optional parameter.
- Allow the ids array to be empty.

In both cases, unconditional selection happen, which is equivalent to
pg_query('SELECT * FROM <table>;').

Two test cases were added to test the aforementioned changes.

Fix broken cache invalidation with deallocated and reallocated document node

The original caching implementation had an oversight in combination with
the new lifetime management in DOM for 8.3.
The modification counter is stored on the document object itself, but as
that can get deallocated when all references disappear, stale cache data
can be used. Normally this isn't a problem, unless getElementsByTagName is
called not on the document but on a child node. Fix it by moving caching
data into the ref object, which will outlive all nodes from a document
even if the document object disappears.

Closes GH-12338.

Implement request #64137 (XSLTProcessor::setParameter() should allow both quotes to be used)

This reimplements the parameter handling. Instead of quoting the strings
manually, adding them to an array, and passing that as input; use the
libxslt API to pass data verbatim to the processor.
This also simplifies the code a lot.

Implement #53655: Improve speed of DOMNode::C14N() on large XML documents

The XPath query is in accordance to spec [1]. However, we can do it in a
simpler way. We can use a custom callback function instead of a linear
search in XPath to check if a node is visible. Note that comment nodes
are handled internally by libxml2 already, so we do not need to
differentiate between node types. The callback will do an upwards
traversal of the tree until the root of the canonicalization is reached.
In practice this will speed up the application a lot.

Reimplement `php_round_helper()` using `modf()` (#12220)

This change makes the implementation much easier to understand, by explicitly
handling the various cases.

It fixes rounding for `0.49999999999999994`, because no loss of precision
happens by adding / subtracing `0.5` before turning the result into an integral
float. Instead the fractional parts are explicitly compared.
