lib: rename bswap_*() to i_bswap()

lib,lib-index: Use #ifdef with WORDS_BIGENDIAN Some were missing from the last change.

global: Use #ifdef instead of #if with WORDS_BIGENDIAN This is to not rely on undefined WORDS_BIGENDIAN being evaluated as 0.

Added "ULL" to the hex literals that needed it. On 32-bit platforms with older compilers (e.g. gcc 4.2 on MacOS 10.6 running on a 1st-gen Core Duo) a 'long' is 4 bytes and the compiler does not automatically use a 'long long' when needed, but instead generates an error. e.g.: libtool: compile: /usr/bin/g++-4.2 -DHAVE_CONFIG_H -I. -I../../.. -I../../../src/lib -I../../../src/lib-mail -I../../../src/lib-index -I../../../src/lib-storage -I../../../src/plugins/fts -I../../../src/doveadm -I/opt/local/include/openssl -I/opt/local/include -I/opt/local/include/CLucene/ext -pipe -Os -arch i386 -D__STDC_LIMIT_MACROS -MT lucene-wrapper.lo -MD -MP -MF .deps/lucene-wrapper.Tpo -c lucene-wrapper.cc -fno-common -DPIC -o .libs/lucene-wrapper.o In file included from ../../../src/lib/lib.h:33, from lucene-wrapper.cc:4: ../../../src/lib/byteorder.h:94: error: integer constant is too large for ‘long’ type ../../../src/lib/byteorder.h:95: error: integer constant is too large for ‘long’ type ../../../src/lib/byteorder.h:96: error: integer constant is too large for ‘long’ type ../../../src/lib/byteorder.h:97: error: integer constant is too large for ‘long’ type make[4]: *** [lucene-wrapper.lo] Error 1 Adding the 'ULL' to the end of the 16-digit hex literals that are used to test the structure of 64-bit integers fixes this and avoids any problem which could arise from the compiler using a 32-bit type for those literals that could fit in 32 bites.

lib: add explicit casts to byteorder macros Some consumers of lib.h are in C++ and therefore they try to compile byteorder.h as C++ code. C++ compilers don't like the implicit void * -> struct anything * conversion, so we squelch those by adding explicit casts.

lib: import byte swapping & endian converting functions

Removed byteorder.* files. They're not used anymore. --HG-- branch : HEAD

Removed the NBO32_BIT* stuff. They don't work well with enums which are signed integers.. --HG-- branch : HEAD

added nbo32_bitmasks[] --HG-- branch : HEAD

Added some network byte ordering functions and macros --HG-- branch : HEAD
