faa75fa19335e3e826efa4f2280609a2db34425d Avoid unsigned integer overflow in bitcoin-tx (MarcoFalke)
Pull request description:
While `npos` means "largest unsigned value" and adding `1` to it yields `0`, it may be clearer to just assign `0` to it and only increment otherwise.
This also allows to remove a file-wide suppression for `unsigned-integer-overflow`.

# This would be `signed-integer-overflow:CTxMemPool::PrioritiseTransaction`,
|
|
# however due to a bug in clang the symbolizer is disabled and thus no symbol

# -fsanitize=integer suppressions
|
|
# ===============================
|
|
# Unsigned integer overflow occurs when the result of an unsigned integer
|
|
# computation cannot be represented in its type. Unlike signed integer overflow,
|
|
# this is not undefined behavior, but it is often unintentional. The list below
|
|
# contains files in which we expect unsigned integer overflows to occur. The
|
|
# list is used to suppress -fsanitize=integer warnings when running our CI UBSan
|
|
# job.
