Eduardo Habkost 0514ef2fbb target-i386: Replace cpuid_*features fields with a feature word array
This replaces the feature-bit fields on both X86CPU and x86_def_t
structs with an array.

With this, we will be able to simplify code that simply does the same
operation on all feature words (e.g. kvm_check_features_against_host(),
filter_features_for_kvm(), add_flagname_to_bitmaps(), CPU feature-bit
property lookup/registration, and the proposed "feature-words" property)

The following field replacements were made on X86CPU and x86_def_t:

  (cpuid_)features         -> features[FEAT_1_EDX]
  (cpuid_)ext_features     -> features[FEAT_1_ECX]
  (cpuid_)ext2_features    -> features[FEAT_8000_0001_EDX]
  (cpuid_)ext3_features    -> features[FEAT_8000_0001_ECX]
  (cpuid_)ext4_features    -> features[FEAT_C000_0001_EDX]
  (cpuid_)kvm_features     -> features[FEAT_KVM]
  (cpuid_)svm_features     -> features[FEAT_SVM]
  (cpuid_)7_0_ebx_features -> features[FEAT_7_0_EBX]

Stefan Weil c7c530cd3e elf: Improve symbol lookup (optimize, fix for bsd-user)
Coverity complained about local variable key which was only partially
initiated. Only key.st_value was set. As this was also the only part
of key which was used in function symfind, the code could be optimized
by directly passing a pointer to orig_addr.

In bsd-user/elfload.c, fix ec822001a2
was missing. This was a simple replacement of > by >= in symfind, so
I fixed it here without creating an additional patch.

Stefan Weil c580dee4e1 bsd_user: Fix potential null pointer dereference
This bug was spotted by cppcheck.

Using g_try_malloc0 (as does the linux-user code) fixes this.

v2:
Use g_free in bsdload.c, too. Thanks to Peter Maydell for this hint.

Stefan Weil 29718712eb bsd-user: Fix possible memory leaks and wrong realloc call
These errors were reported by cppcheck:

[bsd-user/elfload.c:1108]: (error) Common realloc mistake: "syms" nulled but not freed upon failure
[bsd-user/elfload.c:1076]: (error) Memory leak: s
[bsd-user/elfload.c:1079]: (error) Memory leak: syms

v2:
* The previous fix for memory leaks was incomplete (thanks to Peter Maydell for te hint).
* Fix wrong realloc usage, too.

According to $GCC/gcc/config/rs6000/rs6000-c.c _ARCH_PPC is the
ubiquitous define which should be used to test whether gcc targets
PowerPC, on 64bit platforms _ARCH_PPC64 will be also defined.
