Offer clients a `project()`-centric view of the build system. This is
similar to the directory-centric view but consolidates subdirectories
that do not call `project()` with a new project name.

The introduction of policy CMP0082, to run subdirectory install
rules in the correct order, caused a regression in server mode
where any directory with a subdirectory is marked as having an
install rule even if no "real" install rules are present. This
change fixes this regression for server mode.

The `str()` method must be non-const because it may need to internally
mutate the representation of the string in order to have an owned
`std::string` instance holding the exact string (not a superstring).
This is inconvenient in contexts where we can ensure that no mutation
is needed to get a `std::string const&`.
Add a `str_if_stable() const` method that returns `std::string const*`
so we can return `nullptr` if if mutation would be necessary to get a
`std::string const&`. Add supporting `is_stable() const` and
`stabilize()` methods to check and enforce stable availability of
`std::string const&`. These can be used to create `String const`
instances from which we can still get a `std::string const&` via
`*str_if_stable()` by maintaining the stability invariant at runtime.
This will allow creation of `cm::String` instances that borrow from
non-owned storage. It is the caller's responsibility to ensure that
no copy of the instance outlives the borrowed buffer.
Create a `cm::String` type that holds a view of a string buffer and
optionally shares ownership of the buffer. Instances can either
borrow longer-lived storage (e.g. static storage of string literals)
or internally own a `std::string` instance. In the latter case,
share ownership with copies and substrings. Allocate a new internal
string only on operations that require mutation.
This will allow us to recover string sharing semantics that we
used to get from C++98 std::string copy-on-write implementations.
Such implementations are not allowed by C++11 so code our own in
a custom string type instead.
Add support for client-owned *stateful* query files. These allow
clients to request a list of versions of each object kind and get only
the first-listed version that CMake recognizes. Since clients own their
stateful query files they can mutate them over time. As a client
installation is updated it may update the queries that it writes to
build trees to get newer object versions without paying the cost of
continuing to generate older versions.
Issue: #18398
Add support for client-owned stateless query files. These allow clients
to *own* requests for major object versions and get all those recognized
by CMake.
Issue: #18398
Add a file-based API that clients may use to get semantic information
about the buildsystem that CMake generates. Clients will write query
files under a designated location in the build tree, and CMake will
write reply files for clients to read.
Start with support for shared stateless query files. These allow
clients to share requests for major object versions and get all those
recognized by CMake. Once any client has written a shared request to a
build tree it will persist. Other clients will not need to overwrite
the request (since it is stateless) and should not remove it either.
For now we add only an undocumented object kind to use for testing the
query and reply infrastructure. Object kinds providing real semantic
information will be added later.
Issue: #18398
Define a `cm::string_view` type implemented via C++17 `std::string_view`
when available. Provide a fallback implementation for C++11 and C++14
compilers.
The fallback implementation was written by reading documentation of the
standard spec. We have no dedicated tests for it, but it will be
covered by tests of its clients later.
Prior to this commit, linking against an object library did not
propagate private link dependencies of object libraries to their
consuming targets. This change implements the correct behavior.
