75a1093 tests: Fix dangling pwalletMain pointer in wallet tests (Wladimir J. van der Laan)
Tree-SHA512: 7fb6e8385fe7d542f9ecb113a08d675ca9e84907a1939b3a6ad41318fda55bc999b9bc8ffc3f56cd8610ca49d0db982d3c793df7bbcb7eb9638f4483030db6a8
Use of `sprintf` is seen as a red flag as many of its uses are insecure.
OpenBSD warns about it while compiling, and some modern platforms, e.g.
[cloudlibc from cloudabi](https://github.com/NuxiNL/cloudlibc) don't
even provide it anymore.
Although our uses of these functions are secure, it can't hurt to
replace them anyway. There are only 3 occurences left, all in the
tests.
Send payments during the test from a different node than the node generating
keys to be imported, so the spending node doesn't create transactions that
inadvertently involve (spend funds from) the imported keys.
Fixes#9826
This commit fixes the module-level docstrings for the tests and helper
modules in qa. Many of these tests were uncommented previously - this
commit ensures that every test case has at least a minimum level of
commenting.
- Change initializeResult(int) to initializeResult(bool) to avoid
implicit type conversion.
- Use EXIT_FAILURE and EXIT_SUCCESS instead of magic numbers.
- Remove the argument from shutdownResult(int); it was called with a
constant argument.

An effort to reduce the size of AppInitMain().
The removed code upgrades the location of the block files when
upgrading to 0.8. 0.8 seems to be the oldest version still in use.
If the code was compiled with newer (>=3.17) kernel headers but executed
on a system without the system call, every use of random would crash the
program. Add a fallback for that case.
Move the OS random test to a sanity check function that is called every
time bitcoind is initialized.
Keep `src/test/random_tests.cpp` for the case that later random tests
are added, and keep a rudimentary test that just calls the sanity check.
