search_runlen() must know the exact size in bits when parsing
the bits otherwise it read over the buffer.
Fixes testcase #7 which was wrongly decoded.

The 'verify' flag is useless, we always want to verify everything. Replace
'verify' with 'expect_rc', expecting a specific decoding result per test set.
When an error code was returned, cut short the loop and skip printing expected
vs. decoded bits.
This uncovers the fact that the first test marked as "invalid inputs" does not
seem to be invalid after all, or at least does not produce an error to be
returned. For now, only uncover this fact, the fix shall be submitted later.

Before this, the expected data had seemingly random bits set after the end of
the expected decoding result. Make the test expect these extra bits as zero,
matching with the buffer initialization to zero.
In result_matches(), compare the full length of bytes instead of masking the
bits after the end of the decoded data (which caused us to not catch the wrong
expectation until now).
This fixes the underlying issues found in

The test wants to write multiline results, so it should use printf instead of
the logging system.
Split logs to only one hexdump per printf(). One cannot use osmo_hexdump twice
in one printf(); before this, one of the two hexdumps won, both dumps would
show as the same. Very bad for a regression test!
This uncovers a discrepancy between expected and produced results, proving that
the expected stderr output was not capable of uncovering test failures. The
test's check_result() function *has* always verified the decoded data, but only
up to the last decoded bit. Our expected data contains seemingly random bits
after the end of the decoded bits, but check_result() never compares those,
hence we don't catch that error. The extra bits should definitely be zero,
because the destination buffer is pre-initialized to zero -- fixed in a
subsequent patch.
This should cosmetically fix the build failure found in:

The real fix will follow.

Implemented tree based algorithm to decode compressed bitmap in EPDAN
as described in section 9.1.10 of 3GPP 44.060.
This algorithm intends to improve the performance over existing method.
New Regression test is added under bitcomp directory.
Test case is added to validate decompressed result of the bitmap
Present in EPDAN.
Test is done for multiple bitmaps of varying length.
Invalid inputs are also part of the test vector.
