For writing tests, it is often desirable to create a certain situation
that would be tedious, or even impossible to create by sending
individual transactions.
For example, a common attack vector on Solana is to create a copy of
some existing account that stores configuration data, but manipulate the
data stored there, and then to call a program and pass in the
manipulated account, instead of the real account.
If one wants to test this, one option is to write a program that you can
call to write arbitrary data into a new account account (and possibly
change its owner), then include that program in the test context, and
send a transaction to call it. This is extremely tedious, and developers
are not going to bother doing it. I myself would rather fork
solana-program-test to add this `set_account` method, than to write that
program. Having a “god mode” method to just write an account, lowers the
barrier to writing comprehensive tests.
A second reason for introducing this method, is defense in depth. There
may be states of the bank that are not reachable *yet* by only sending
transactions, but that you might want to test against either way. For
example, right now, the balance of a stake account cannot decrease
without going through the stake program. But what if Solana were to
introduce slashing in the future, and you want to ensure your program is
robust against decreases in stake account balance? Right now there is no
way to test this, but by introducing this “god mode” to write accounts,
the situation becomes testable.

* document ProgramTest::new
* simplify ProgramTest::new doc-string
* make ProgramTest::add_program noisier
`add_program` (and `new`, implicitly) now prints a warning when the user
supplies a bogus program name to a ProgramTest and invokes `test-bpf`.
Additionally, it is now impossible to ask for a regular `test` and for
the generated ProgramTest to load BPF code instead of native code.
Previously, this was caused by a precedence issue: BPF code would always
be preferred over native if the program name was valid, regardless of
user choice.

Since program-test creates a test genesis and then adds fees and rent,
some of the genesis accounts get rent-collected after warping. Most
notably, `StakeConfig` gets rent-collected, causing any stake operations
to fail after warp. This fix creates genesis with the `Rent` and
`FeeRateGovernor` actually used by the bank.
