f7e7bd4c3b Suppress false positive memory leak warnings.
Clang static analyzer does not know the transfer of
object ownership to hashmapPut. Use a fake global
pointer variable to trick the analyzer.

7390478f19 libcutils: cleanups for -fsanitize=integer
Hash functions rely on overflow behavior, so whitelist them.

ATRACE_TAG_NOT_READY: use an unsigned constant when shifting bits.
Otherwise, the value overflows on shift. The users of this constant
assign it to a uint64_t variable.

af98efbd15 Move all libcutils tests into the gtests.
This also fixes the bug where we were always testing against the fake
strlcpy we provide for glibc/Windows rather than the Android one.

This also removes some unnecessary library dependencies.

This also builds all the cutils tests for the host (static and dynamic).

d3c8d5b8d4 Handle errno properly to avoid corrupt str_parms
A normal sequence of calls is as follows:
str_parms_create_str, str_parms_add_str, str_parms_destroy.
In some cases the destroy caused double free.

str_parms_add_str will clone the input and send it to hashmapPut
for storage. If hashmapPut did not store the strings it will raise
errno = ENOMEM and leave caller with ownership of the strings.
In any of these cases it will be safe to destroy the str_parms.

But what if it wasn't hashmapPut that said NOMEM? What if there
was a stale NOMEM already before a successful hashmapPut?
In that case the strings will be successfully added to the list
(if new), but when str_parms_add_str sees the NOMEM it will free
them anyway, leaving dangling pointers in the str_parms!!

It is the responsibility of the caller to clear errno before any
interesting call. This patch makes sure that str_parms_add_str
reacts only on errno emmitted from hashmapPut.

b957baccd2 libcutils: bug str_parms.c:str_parms_get_float().
str_parms_get_float did not return the output into
*val. Only output if returning with no error. Audit
shows no internal users of this library function

efd7501d53 cutils: str_parms: when deleting entry, need to also remove key
When removing one entry, we can't just remove it from the map since
key will not be freed. So, instead, search through the map for the key
and free it once it is found.
