The current implementation of bpf_obj_get doesn't follow libbpf semantics,
because it always returns -1 on error, instead of returning the negative
error number.
This is especially noticeable when trying to open a non-existant object,
which should return -ENOENT.
See caa17bdcbf/src/bpf.c (L625-L626)
* remove --no-verify option from bpf2c and tests using it
Closes#3571
* remove builds for unsafe programs in sample.vcxproj
* remove unsafe test cases from netsh_test.cpp
* remove new noverify references
* Revert deletion of netsh tests.
* Add back compilation of unsafe programs (but not bpf2c call)

* Move C++ hashing lib from tests/libs/util/ to libs/shared/
This puts hash.cpp/hash.h in a more central location for use by other project files.
* Set empty program name to hash of instructions
ebpf_program_load_bytes now hashes the instructions and uses that for the name
instead of generating a random number.
Closes#3443
* fix signed/unsigned warning (and ensure windows helper id >= 0)
* add bcrypt.dll dependency for ebpfapi.dll
* WIP new test case for ebpf_program_load_bytes with nullptr program name
* WIP ebpf_program_load_bytes testing
* truncate SHA256 hash to 63 bytes to stay under BPF_OBJ_NAME_LEN
* remove bcrypt from release dependencies and suppress analyze warning

* Fix code analysis annotations for _In_ and _In_opt_ parameters,
add const where appropriate or change to _Inout_ where appropriate.
The following regex expressions were used to find the problems:
Find _In_ or _In_opt_ that are not const and are not followed by _Post_invalid_ or _Frees_ptr_ or _Post_ptr_invalid_:
```_In_[ ]+(?!.*(const|_Post_invalid_|_Frees_ptr_|_Post_ptr_invalid_))```
```_In_opt_[ ]+(?!.*(const|_Post_invalid_|_Frees_ptr_|_Post_ptr_invalid_))```
Some of the _In_ and _In_opt_ parameters are not const due to required compatibility with the Windows API.
Pointers to functions are const by definition, so the const qualifier is not required.
