Prior to this commit, Spring Framework's JSP form tags supported the
response encoding in most places; however, <form:select> and
<form:options> still did not support the response character encoding.
To address that, this commit updates SelectTag, OptionsTag, and
OptionWriter to provide support for response character encoding in the
`select` and `options` JSP form tags.

Prior to this commit, a NoUniqueBeanDefinitionException was thrown when
multiple primary beans were detected within a given set of beans, but
nothing was logged. For use cases where the exception is handled by
infrastructure code, it may not be obvious to the developer what the
problem is.
To address that, a TRACE message is now logged whenever multiple
competing primary beans are detected in DefaultListableBeanFactory.

This commit fixes code generation for a bean produced by a protected
factory method. Previously only the code generated for public methods,
i.e. without a dedicated instance supplier method, was handled.

The compiler has a constants pool limit of 65536 entries per source file
which can be hit with a very large amount of beans to register in the
bean factory.
This commit makes sure to create separate source files if the number
of beans to register is very large. The main generated source file
delegate to those.
Closes gh-35044
Prior to this commit, argument index handling in
AutowiredArgumentsCodeGenerator suffered from an off-by-one error when
generating code for an autowired inner class constructor.
Since the startIndex is already properly calculated for an inner class in
InstanceSupplierCodeGenerator.buildGetInstanceMethodForConstructor(...),
there is no need to adjust the argument indexes within
AutowiredArgumentsCodeGenerator.generateCode(...).

After the bootstrap phase (and with spring.locking.strict=true during the bootstrap phase), getSingletonFactoryBeanForTypeCheck always locks. In a background bootstrap thread, it never locks. Otherwise, it tries locking and explicitly resolves the bean class for subsequent type-based resolution (even for a component-scanned class) when it fails to acquire the lock. Furthermore, getObjectFromFactoryBean follows the same locking algorithm for post-processing.

Spring Framework 6.2 introduced support for an escape character for
property placeholders (by default '\'). However, as of Spring Framework
6.2.6, there was no way to either escape the escape character or disable
escape character support.
For example, given a `username` property configured with the value of
`Jane.Smith` and a `DOMAIN\${username}` configuration string, property
placeholder replacement used to result in `DOMAIN\Jane.Smith` prior to
6.2 but now results in `DOMAIN${username}`. Similarly, an attempt to
escape the escape character via `DOMAIN\\${username}` results in
`DOMAIN\${username}`.
In theory, one should be able to disable use of an escape character
altogether, and that is currently possible by invoking
setEscapeCharacter(null) on AbstractPropertyResolver and
PlaceholderConfigurerSupport (the superclass of
PropertySourcesPlaceholderConfigurer).
However, in reality, there are two hurdles.
- As of 6.2.6, an invocation of setEscapeCharacter(null) on a
PropertySourcesPlaceholderConfigurer applied to its internal
top-level PropertySourcesPropertyResolver but not to any nested
PropertySourcesPropertyResolver, which means that the `null` escape
character could not be effectively applied.
- Users may not have an easy way to explicitly set the escape character
to `null` for a PropertyResolver or
PropertySourcesPlaceholderConfigurer. For example, Spring Boot
auto-configures a PropertySourcesPlaceholderConfigurer with the
default escape character enabled.
This first issue above has recently been addressed by gh-34861.
This commit therefore addresses the second issue as follows.
- To allow developers to easily revert to the pre-6.2 behavior without
changes to code or configuration strings, this commit introduces a
`spring.placeholder.escapeCharacter.default` property for use with
SpringProperties which globally sets the default escape character that
is automatically configured in AbstractPropertyResolver and
PlaceholderConfigurerSupport.
- Setting the property to an empty string sets the default escape
character to `null`, effectively disabling the default support for
escape characters.
spring.placeholder.escapeCharacter.default =
- Setting the property to any other character sets the default escape
character to that specific character.
spring.placeholder.escapeCharacter.default = ~
- Setting the property to a string containing more than one character
results in an exception.
- Developers are still able to configure an explicit escape character
in AbstractPropertyResolver and PlaceholderConfigurerSupport if they
choose to do so.
- Third-party components that wish to rely on the same feature can
invoke AbstractPropertyResolver.getDefaultEscapeCharacter() to obtain
the globally configured default escape character.

Specifically, the documentation update reflects that:
- Initially, it was mentioned that only the `BeanFactoryAware`
interface is ignored by default.
- The updated documentation now correctly states that `BeanNameAware`,
`BeanFactoryAware`, and `BeanClassLoaderAware` interfaces are all
ignored by default.
This change ensures a more accurate representation of the default
behavior regarding which dependency interfaces are automatically
ignored during autowiring in the context of Spring's bean factory
mechanism.

- ClassUtils.isAssignable(): Avoid Map lookup when the type is not a
primitive.
- AnnotationsScanner: Perform low cost array length check before String
comparisons.
- BeanFactoryUtils: Use char comparison instead of String comparison.
The bean factory prefix is '&', so we can use a char comparison
instead of more heavyweight String.startsWith("&").
- AbstractBeanFactory.getMergedBeanDefinition(): Perform the low cost
check first. Map lookup, while cheap, is still more expensive than
instanceof.
