This commit modifies the `DefaultDatabaseClient` implementation in order
to ensure lazier usage of the `Supplier<String>` passed to the sql
method (`DatabaseClient#sql(Supplier)`).
Since technically `DatabaseClient` is an interface that could have 3rd
party implementations, the lazyness expectation is only hinted at in the
`DatabaseClient#sql` javadoc.
Possible caveat: some log statements attempt to reflect the now lazily
resolved SQL string. Similarly, some exceptions can capture the SQL that
caused the issue if known. We expect that these always occur after the
execution of the statement has been attempted (see `ResultFunction`).
At this point the SQL string will be accessible and logs and exceptions
should reflect it as before. Keep an eye out for such strings turning
into `null` after this change, which would indicate the opposite.

Includes deprecation of NestedServletException, whereas NestedCheckedException and NestedRuntimeException remain as base classes with several convenience methods.
Closes gh-25162
Adopt to R2DBC Parameter type, deprecate our own one in favor of the R2DBC type.
Add support for extensible transaction definitions and support to consume Readable and result segments.
Return Long instead of Integer in DatabaseClient update in preparation for R2DBC 1.0 changes.
Prior to this commit, H2SequenceMaxValueIncrementer only supported H2
database 1.4.
This commit updates H2SequenceMaxValueIncrementer's getSequenceQuery()
method so that the syntax used supports version 1.4 and 2.0 of the H2
database.
This commit also updates several test schemas so that they work with H2
1.4 and 2.0 as well as HSQL.

Prior to this commit, many of the utility methods in ScriptUtils in
spring-r2dbc were public by accident: they were copied from ScriptUtils
in spring-jdbc without changing the visibility when spring-r2dbc was
introduced in Spring Framework. 5.3 GA.
This commit corrects this mistake by removing internal APIs from
ScriptUtils in spring-r2dbc from the public contract.
See gh-26947
Prior to this commit, the implementations of
ScriptUtils.containsSqlScriptDelimiters() in spring-jdbc and
spring-r2dbc did not ignore comments when searching for the statement
delimiter within an SQL script. This resulted in subtle bugs if a
comment contained a single single-quote or single double-quote, since
the absence of the closing single-quote or double-quote led the
algorithm to believe that it was still "within a text literal". Similar
issues could arise if a comment contained the sought statement
delimiter but the rest of the script did not contain the sought
statement delimiter. In such cases, the algorithms in ScriptUtils could
erroneously choose an incorrect statement delimiter -- for example,
using the fallback statement delimiter instead of the delimiter
specified by the user.
This commit avoids such bugs by ignoring single-line comments and block
comments when searching for the statement delimiter within an SQL
script.
Closes gh-26911
Prior to this commit, the containsSqlScriptDelimiters() method in
ScriptUtils ignored delimiters enclosed in single quotes but not those
enclosed within double quotes, which contradicts the algorithm in
splitSqlScript() and therefore constitutes a bug.
This commit fixes this bug in the ScriptUtils implementations in
spring-jdbc and spring-r2dbc.

We now support Oracle's bind marker scheme that identifies dynamic
parameters using names that are prefixed with a colon such as
`:P0_myparam`.

This commit raises the minimum Coroutines version supported
to 1.4.0-M1 and above, and changes usages of awaitFirst() or
awaitFirstOrNull() to awaitSingle() or awaitSingleOrNull()
to fix gh-25007.

This commit introduces support for R2DBC ("Reactive Relational Database
Connectivity") with custom ConnectionFactory implementations, a
functional DatabaseClient for SQL execution, transaction management, a
bind marker abstraction database initialization utilities, and
exception translation.
Closes gh-25065
