selftests/bpf: fix some typos in selftests
...
Hi, fix some spelling errors in selftest, the details are as follows:
-in the codes:
test_bpf_sk_stoarge_map_iter_fd(void)
->test_bpf_sk_storage_map_iter_fd(void)
load BTF from btf_data.o->load BTF from btf_data.bpf.o
-in the code comments:
preample->preamble
multi-contollers->multi-controllers
errono->errno
unsighed/unsinged->unsigned
egree->egress
shoud->should
regsiter->register
assummed->assumed
conditiona->conditional
rougly->roughly
timetamp->timestamp
ingores->ignores
null-termainted->null-terminated
slepable->sleepable
implemenation->implementation
veriables->variables
timetamps->timestamps
substitue a costant->substitute a constant
secton->section
unreferened->unreferenced
verifer->verifier
libppf->libbpf

selftests/bpf: adjust global_func15 test to validate prog exit precision
...
Add one more subtest to global_func15 selftest to validate that
verifier properly marks r0 as precise and avoids erroneous state pruning
of the branch that has return value outside of expected [0, 1] value.

bpf: enforce precise retval range on program exit
...
Similarly to subprog/callback logic, enforce return value of BPF program
using more precise smin/smax range.
We need to adjust a bunch of tests due to a changed format of an error
message.

selftests/bpf: Convert test_global_funcs test to test_loader framework
...
Convert 17 test_global_funcs subtests into test_loader framework for
easier maintenance and more declarative way to define expected
failures/successes.

selftests/bpf: Add unit tests for pointers in global functions
...
test_global_func9 - check valid pointer's scenarios
test_global_func10 - check that a smaller type cannot be passed as a
larger one
test_global_func11 - check that CTX pointer cannot be passed
test_global_func12 - check access to a null pointer
test_global_func13 - check access to an arbitrary pointer value
test_global_func14 - check that an opaque pointer cannot be passed
test_global_func15 - check that a variable has an unknown value after
it was passed to a global function by pointer
test_global_func16 - check access to uninitialized stack memory
test_global_func_args - check read and write operations through a pointer
