Log Message:
-----------
Crash in ISOProtectionSystemSpecificHeaderBox::parse with large keyID counts
https://bugs.webkit.org/show_bug.cgi?id=258174
rdar://110412566
Reviewed by Jean-Yves Avenard.
KeyID is 16 bytes, so it's possible for a `pssh` box to specify a `keyIDCount`
large enough that the
following keyIDs array cannot be contained by a Vector. To account for this,
try to reserve capacity
for `keyIDCount` in m_keyIDs before resizing and return `false` if the
reservation fails.
