The ALLOCA(3) man-page mentions its "use is discouraged".
Replace few calls by equivalent GLib malloc().

Since v2:
- linux-user calls converted
- bsd-user returns ENOMEM (Peter)
- built on PPC+KVM host (David)
- removed tpm mutex cleanup (Christophe)
- included Alex gdbstub patch
- added R-b tags

Since v1:
- Converted more uses (alsaaudio, tpm, pca9552)
- Reworked gdbstub (Alex)
- Simplified PPC/KVM (Greg)

Alex Bennée (1):
  gdbstub: Replace GdbCmdContext with plain g_array()
